2010 National Medal of Science Recipient for Physical Science and Co-Director of the Institute for Quantum Studies; James. J Farley Professor of Natural Philosophy

aharonov@chapman.edu
Dr. Aharonov has discovered more than 30 fundamental physics effects, many concerning quantum phases. The topological nature of quantum phases (which are independent of the space-time paths of the encircling particles) makes them robust and useful tools for many fields of physics.

### Distinguished Visiting Professors in Residence

Sir Michael Berry, FRS

Melville Wills Professor of Physics (Emeritus), University of Bristol

Sir Michael Berry is well known for the discovery of the Berry-phase, the sister-phenomenon to the Aharonov-Bohm phase. Thomson-Reuters not long ago conducted a worldwide poll of scientists, in which Aharonov, along with Institute member Sir Michael Berry, were voted #1 most likely to win a Nobel Prize in physics in coming years.

Dr. Aharon Casher

Professor Emeritus in School of Physics and Astronomy, Faculty of Exact Sciences

Aharon Casher is renowned for his work particle physics and foundations of quantum theory, specifically on understanding super-symmetry at the level of field theory, along with his work on the fundamentals of field theory and quantum gravity. His most cited publications include the Aharonov-Casher effect along with papers concerning spontaneous chiral symmetry breaking in quantum chromo-dynamics.

Dr. Paul Davies

Paul Davies' research has focused on some of the biggest questions of existence with revolutionary impact, ranging from the origin of the universe to the origin of life, the deep nature of reality, the mysteries of time, and the realm of quantum physics.

Brad Dodrill

Brad C. Dodrill graduated from The Ohio State University in 1982 with a BSc degree in Physics and a minor in Mathematics. He completed 2 years of graduate studies in Physics and Electrical Engineering and took a position with Lake Shore Cryotronics in 1984 as a Research Scientist. He is presently the Vice President of Sales and a Senior Scientist at Lake Shore. In his technical capacity he is active in applications and product development initiatives in the areas of magnetic and electronic measurements and materials. He has 36 paper publications to his credit, holds 3 US patents, and has lectured at numerous universities and technical conferences in the US, Europe and Asia on Vibrating Sample Magnetometry, AC Susceptometry, Alternating Gradient Magnetometry and on the use of the First-Order-Reversal-Curve (FORC) measurement and analysis technique for the characterization of the magnetic properties of materials.

Dr. Francois Englert

Dr. David Gross

Professor David Gross has been a central figure in the theoretical developments surrounding the emergence of quantum chromodynamics as the accepted theory of the strong nuclear force. He was awarded the 2004 Nobel Prize in Physics for this discovery.

Sir Anthony Leggett

Professor Leggett’s pioneering work on superfluidity was honored with the 2003 Nobel Prize.

Dr. Shmuel Nussinov

Shmuel Nussinov has over 300 publications, Nussinov’s main interests are in high energy physics - in particular the physics of hadrons’ strongly interacting particles, the physics of neutrinos. In addition he is interested in astroparticle - an interdisciplinary area bridging astrophysics and particle physics and the dark matter problem - namely that we do not know as yet what most of the matter in the universe is comprised of. In addition, he has been working on foundational issues in quantum mechanics and field theory.

Dr. Sandu Popescu

Professor of Physics, University of Bristol

Sandu Popescu is well known as one of the founders of, and most active researchers in, quantum information. Popescu's work has completely changed the subject of quantum entanglement and nonlocality. He helped create the quantitative approach to entanglement which became the central paradigm of the field, namely “entanglement as a resource”. He also pioneered research on multi-partite entanglement and on the nonlocality of interactions (rather than of states) and was the first to extend the notion of non-locality beyond quantum mechanics. The study of super-quantum nonlocal correlations (the so called Popescu-Rohrich correlations) is at present an entire research area by itself. With Massar, he initiated the area of quantum state estimation. With Gisin he initiated the subject of alignment of frames of reference by quantum means. He also initiated the area of entangled photons spectroscopy. Popescu also has had very successful interactions with experimentalists: for example, he designed the experimental scheme for the first quantum teleportation experiment. Finally, Popescu conducted seminal work on the foundations of statistical mechanics, showing from first principles, that every system in contact with a much larger one (bath) reaches equilibrium (a“holy grails” of the subject).

Dr. Lenny Susskind

Leonard Susskind is well known for his fundamental work in quantum field theory, quantum cosmology and string theory.

Dr. Lev Vaidman

### Senior Research Scientist

Dr. Armen Gulian

Armen Gulian’s scientific carrier began with a PhD and post-doctoral research on non-equilibrium phenomena in superconductors and superfluids with Nobel Laureate Vitaly Ginzburg. His 70 refereed publications include: predicting the “phonon deficit” effect (important for development of electronic coolers); theory of superconducting quantum generators (potential application for terahertz radiation imaging and high-resolution acoustic imaging); prediction of interference current at hydrodynamic description of superconductivity (important for superconducting nano-wires). Before setting up the Advanced Physics Laboratory for Chapman, Dr. Gulian founded the Laboratory of High-Temperature Superconductivity at the Physics Research Institute, Armenia (world’s first observation of phase-slip centers in high-temperature superconductors) and thereafter worked on development of quantum detectors at the US Naval Research Laboratory. There he suggested a theoretical design and demonstrated experimentally the cryogenic detector prototypes for X-ray/UV single-photons.

### Affiliated Scholars with the Institute for Quantum Studies at Chapman University

Dr. Fabrizio Colombo

Affiliated Scholar with the Institute for Quantum Studies

Interests: the mathematics of superoscillations, inverse problems for materials with memory, spectral theory for n-tuples of operators and for quaternionic operators, hypercomplex analysis and its applications.

Andrew Jordan

Professor of Physics, University of Rochester; Affiliated Scholar with the Institute for Quantum Studies

Prof. Jordan received his B.S. in Physics and Mathematics (1997) from Texas A&M University and his Ph.D. in Theoretical Physics (2002) from the University of California, Santa Barbara. He was a postdoctoral fellow at the University of Geneva (2002-2005) and a research scientist at Texas A&M (2005-2006). He joined the University of Rochester as Assistant Professor of Physics in 2006, and was promoted to Associate Professor with Tenure in 2012.

Professor Jordan is a member of the Center for Quantum Information and the Rochester Theory Center for Optical Science and Engineering.

Professor Jordan joined the Institute of Quantum Studies at Chapman University as an Affiliated Scholar in 2012.

Research: Prof. Jordan's research interests are in theoretical Quantum Physics, Condensed Matter Physics, and Quantum Optics. Themes of interest include nanophysics, the theory of weak quantum measurement, quantum information, and random processes in nature. Nanophysics addresses fundamental physical problems that occur when a macroscopic object is miniaturized to dimensions at the nanometer scale. The theory of weak quantum measurement makes predictions about the random nature of continuous measurements made over some time period, and how these measurements are useful for the purposes of processing quantum information. Recent results include how to uncollapse the wavefunction, the statistical properties of single-electron currents through a quantum dot, and the use of weak values as precision optical amplifiers.

Dr. Domenico Napoletani

Professor, Research Faculty, and Affiliated Scholar with the Institute for Quantum Studies

Domenico Napoletani is a mathematician, theoretical biologist and a research professor at Chapman University. His most recent work proposes a theoretical setting for the study of robustness in biological systems by adapting phase and path integrals techniques to the study of high dimensional classification functions. A parallel line of research is the study of the problem of reconstructing and controlling protein networks structure from limited, noisy reverse phase protein array data sets. Dr. Napoletani's guiding methodological viewpoint is to attempt a profound cross-fertilization of signaling processing and dynamical systems techniques, and to approach signaling networks’ problems with weak assumptions. He has also explored the epistemological implications of these methodologies, suggesting a series of paradigms to structure the large body of data analysis research into a common framework.
