    Descriptive info: image caption: Approximately 10,000 atoms in a Bose-Einstein condensate that has been split into two packets separated by about 0.. 5 mm.. Each atom is simultaneously in each packet.. Experimental Atomic, Molecular, and Optical Physics.. The fundamental goal of essentially all atomic and molecular physics is a complete understanding of the interactions of atoms and molecules with electromagnetic fields.. These fields may be static or dynamic, originating within the atoms or molecules, or external to them.. The experimental Atomic and Molecular groups in the Department of Physics use a wide variety of laser, electro-optical, and microwave equipment to study and manipulate the properties of atoms, molecules, and clusters.. As a result, their work is closely connected to the field of optical physics.. Optical physics is the study of the generation of optical radiation, the properties of that radiation, and the manipulation and control of radiation by matter.. Current research in optical physics includes the development of novel light sources and the exploitation of the quantum properties of light for non-classical communication and precision measurements.. The particular research specialization of individual faculty members in the AMO group is summarized below.. Read More about Experimental Atomic, Molecular, and Optical Physics at UVa.. Return to Short Description.. Bloomfield s research group studies clusters, small aggregates of atoms that fall in between atoms and solids.. His group is particularly interested in two areas of cluster science: the study of magnetism in isolated metal clusters and the study of electronic structure in insulator clusters.. Their work on magnetism in metal clusters seeks to connect atomic and molecular magnetism with that of condensed matter.. Gallagher s research focuses on highly excited Rydberg atoms.. These atoms interact strongly with external perturbations providing opportunities to quantitatively explore otherwise inaccessible phenomena.. Currently the group is investigating microwave multiphoton excitation and ionization with few-cycle microwave pulses, studying collisions between cold (1 milliKelvin) Rydberg atoms in a magneto-optical trap, and examining energy flow between different electronic configurations in atoms with two optically active electrons.. Jones and his students use intense electromagnetic pulses with durations as short as 25 femtoseconds to investigate and control quantum dynamics within atoms and molecules.. Current efforts include the development of new techniques for imaging the evolution of electronic wavefunctions within atoms and the position of nuclei within molecules, the control of electron-electron scattering within atoms through the creation of two-electron wavepackets with specific dynamical properties, the use of intense laser pulses to align and/or orient molecules in free space, the generation of coherent, vacuum ultraviolet femtosecond light pulses; and the use of unipolar, THz frequency electric field pulses to simulate coherent charged-particle/atom collisions.. Pfister s research interests include molecular spectroscopy, nonlinear and quantum optics, and quantum information.. His group is especially interested in experimental realizations of quantum information protocols using parametric oscillators and two-photon lasers as intense ultrastable sources of entangled photons.. Other interests  ...   to such research is the study of spin interactions during atomic collisions, spin-relaxation at surfaces, and numerous aspects of laser physics.. Gallagher:.. Highly excited, or Rydberg, atoms interact strongly with external perturbations, providing Prof.. Gallagher s group with opportunities to quantitatively explore otherwise inaccessible phenomena.. They are studying the interaction of Rydberg atoms with microwave fields which have frequencies comparable to the Kepler orbital frequency of the electron, a regime in which many phenomena exhibit both classical and quantum behavior.. They are examining the properties of relatively high density samples of cold Rydberg atoms using a magneto optical trap.. These samples can behave as disordered.. Jones:.. Much of the current research in atomic physics focuses on the use of extremely well-controlled electromagnetic fields to coherently manipulate the internal and external degrees of freedom of atoms.. Jones and his students use lasers to cool and trap atoms, to spin molecules in order to align their axes along a particular direction in the laboratory, and to drive electrons within atoms and molecules in particular directions at specific times.. These optical techniques serve as tools which allow them to view very fast processes within atoms and molecules and to perform experiments exploring.. Lehmann:.. High Resolution Laser Spectroscopy: Development of double resonance techniques for the study of excited vibrational and electronic states of polyatomic molecules; spectroscopy and dynamics of atoms and molecules in helium and molecular hydrogen nanoclusters, determination of the magnitude of intermode coupling constants or intramolecular relaxation rates; development of new spectroscopic methods of extreme sensitivity; development of new sources of tunable, high spectral brightness light; spectroscopic applications to environmental monitoring.. Pfister:.. Olivier Pfister s research focuses on experimental quantum optics and quantum information.. The quantum nature of light (the existence of photons) is a fascinating subject which has turned into a mature experimental field since its inception in the eighties.. The research by Pfister s group,.. Quantum Fields and Quantum Information.. (QFQI), aims at blazing new trails into the realm of quantum information.. In particular, QFQI and their theory collaborators, Nicolas Menicucci and Steven Flammia at the.. Sackett:.. Since its first observation in 1995, the process of Bose-Einstein condensation of atomic gases has captured the imagination of many physicists.. In this phenomenon, a large number of atoms come to occupy the same quantum state, causing the normally ethereal wave function to act rather as a classical, observable wave.. Our research is focused on developing practical applications for these condensates.. In particular, we are developing condensate interferometry, in which the atom wave is coherently separated into pieces which are later recombined.. The result of the recombination depends.. FACULTY..

Condensed matter physics seeks to understand the striking new physical properties that may emerge when very large numbers of atoms or molecules organize into solids or liquids.. Research in this area has led to fundamental breakthroughs in our understanding of metals, semiconductors and superconductors, as well as to the inventions of the transistor, diode laser, and integrated circuit.. Condensed matter physics thus comprises the technological underpinning for the entire modern computer and communications industry.. For these reasons, worldwide, this branch of physics commands the largest number of researchers, who work in academic institutions, major industrial and government laboratories, and small entrepreneurial enterprises.. The problems addressed by condensed matter physicists are often interdiscplinary in nature, affecting a number of other scientific fields including chemistry, biology, electrical engineering, and materials science.. The University of Virginia maintains a diverse and vigorous research program in both experimental and theoretical condensed matter physics.. Read More about Experimental Condensed Matter Physics at UVa.. The experimental condensed matter research groups at UVa explore the structural, optical, electronic, and magnetic properties of different types of solids ranging from amorphous to crystalline systems with unusual properties.. Activities include the synthesis and characterization of metallic glasses, quasicrystals, colossal magnetoresistive manganites and high temperature superconductors, measurements of electronic and magnetic properties of new intermetallic compounds, characterization of static and dynamic lattice effects in oxides, intermetallic alloys and martensites using the pair density function analysis, study of the microscopic processes at the interface of two relatively sliding materials as well as inside metals and crystals during plastic deformation, study of phase transitions, measurement of magnetic and quantum correlation effects in heavy fermion and high-temperature superconductors, scanning-probe and optical studies of new semiconductor alloys, studies of wetting and adsorption on crystal surfaces, and development of far-infrared applications of semiconductors and superconductors.. The condensed matter community at UVa has access to a variety of cryogenic facilities capable of scanning temperatures from as low as 15 mK to room temperature, several high-field magnets, a quantum-interference magnetometer, different scanning-probe instruments such as scanning tunneling, force, and optical microscopes, various vacuum thin-film deposition and etching systems, and a range of microwave and millimeter-wave analytic instruments.. In addition, many research projects work closely with Electrical Engineering and Materials Science Departments, using facilities such as a photolithography lab and X-ray diffraction and elec-tron-beam microscopes, as well as national labs where high magnetic fields sources are available.. The group also performs research at national and international neutron and x-ray facilities and carries out high precession measurements on the atomistic properties of materials particularly under high pressure..

The materials studied.. Shivaram:.. Professor Shivaram is a condensed matter experimentalist whose research spans a wide variety of key areas.. His earlier work focused on the properties of Quantum Fluids at very low temperatures and high magnetic fields.. His recent work has focused on the thermodynamic, electromagnetic and acoustic properties of a class of compounds based on rare earth and actinide elements, called the heavy electron metals.. Strong electronic correlations in these metals give rise to many exotic phenomena in these systems such as unconventional superconductivity and magnetism.. More recently, Professor.. Wolf:.. My primary interest at UVa is in the study of spin dependent phenomenon in thin films and alternating multilayers of magnetic and non-magnetic metals, semiconductors and insulators.. These structures exhibit large changes in resistance depending on the relative orientation of the magnetic layers..

    Descriptive info: image caption:.. Experimental Nuclear and Particle Physics.. The Physics Department and the Institute of Nuclear and Particle Physics support some of the leading research groups in this basic area of physics.. Faculty members are the spokesmen for experiments that test fundamental aspects of nucleon and nuclear structure.. These include experiments at the Stanford Linear Accelerator Center (SLAC) on the origin of the nucleon's spin, the details of the charge distribution of the neutron at Thomas Jefferson National Accelerator Facility (TJNAF), and a precision measurement of pion beta decay at the Paul Scherrer Institute (PSI).. At SLAC the inelastic scattering of polarized electrons from polarized nucleon targets allows a detailed investigation of the spin structures of the nucleon.. These measurements provide the best determination of how the quarks and gluons contribute to the fundamental spin of the nucleon.. There is active research and development of high-power polarized targets, using high-field superconducting magnets, low-temperature refrigerators, and high-frequency microwaves.. Electron paramagnetic resonance characterization of these targets is proceeding together with theoretical and computational modeling of local hyperfine interactions that contribute to dynamic nuclear polarization.. At TJNAF an extensive series of experiments has been approved, including a measurement of the electric charge form factor of the neutron.. The experimental measurements are complemented by strong theoretical support in the Department.. This theoretical effort involves work in relativistic chiral quark models; spontaneous chiral symmetry breaking; quantum theories based on light-front formalism; and perturbative quantum chromodynamics (QCD) phenomenology, including studies of power corrections to the nucleon/nuclear structure functions, quark-hadron duality and low Bjorken x physics.. Read More about Experimental Nuclear and Particle Physics at UVa.. The measurement of both the electron and hadron in electromagnetic nuclear reactions will provide new information about possible modifications of nucleon structure within the nuclear medium.. The additional ability to measure the spin of the recoiling hadron with a polarimeter allows a determination of nuclear dynamics not accessible by standard methods.. Experiments at TJNAF use resonant pion production from the nucleon to study the structure and inelastic response of this fundamental three-quark system.. Electro-production of excited states of the nucleon constitutes a major part of the research program for the large acceptance detector (CLAS).. This detector consists of a large toroidal superconducting magnet, with a variety of detectors to track and identify particles over a large solid angle.. Polarized nucleon targets have been developed for use in this detector.. The study of basic symmetries and conservation laws can provide some of the most precise information on the dynamics of the two short-range interactions, the electroweak and the strong.. A precision measurement of the pion beta decay rate is taking place at PSI in Switzerland.. This measurement provides the best theoretical means to study the weak coupling between the up and down quarks.. A program of experiments at the Laser Electron Gamma Source (LEGS) at Brookhaven National Laboratory examines the non-perturbative regime of QCD, including the possible resonant distortion of the nucleon.. This work is complemented by research at the newly-commissioned low energy polarized photon source at the Triangle Universities Nuclear Laboratory (TUNL).. Baeßler:..

The funds also provided for a new scattering chamber and target cells.. The large acceptance (90 msr) spectrometer and.. Liyanage:.. In the so called confinement region quarks interact strongly to form protons and neutrons.. Understanding the structure of the nucleon in the confinement region in terms of Quantum Chromo Dynamics (QCD), the fundamental theory governing the strong interaction between quarks, presents a great challenge to physicists.. Professor Liyanage s research is focused on understanding the neutron structure.. He is the principal spokesperson of a recently completed Jefferson Lab experiment, E01-012, that performed a precision measurement of the neutron spin structure in the nucleon resonance.. Norum:.. Quantum Chromo-Dynamics (QCD) provides an excellent description of subnuclear phenomena at high energies.. However, at lower energies observables cannot be calculated exactly from QCD; one has to resort to models or parametrizations which are consistent with the basic symmetries of QCD.. Near-threshold electromagnetic production of pions from nucleons are ideal processes in which to test these theoretical approaches.. We are engaged in measuring these processes at the Jefferson Laboratory (JLab) and at the new High Intensity Gamma Source (HIGS) located at the Duke Free Electron Laser.. Paschke:.. Professor Paschke s research activity focuses on precision measurements of parity-violation in electron scattering at Jefferson Lab, in Newport News Virginia.. These measurements have proven to be a useful tool for the study of the building blocks of the atomic nucleus and for testing the completeness of the Standard Model of electroweak interactions.. A recently completed series of experiments address a range of topics, including strange quarks in nuclei, nuclear structure in a.. 208.. Pb nucleus, and the electroweak coupling of the nucleons..

Professor Zheng conducts research at the Thomas Jefferson National Accelerator Facility (JLab).. Her research interest includes study of the nucleon structure, especially the spin structure of the neutron using the polarized 3He target..
