Strong Fermion Interactions in Fractional Quantum Hall States (eBook)

John J. Quinn is a well-known theoretical physicist as well as an academic administrator; he is a former Chancellor and a professor emeritus since 2015 at the University of Tennessee, Knoxville, USA. He is an expert in the areas of condensed matter physics and many-body theory including two dimensional Composite fermions, low-dimensional systems, quantum Hall effect and nanoscience. Quinn was also one of the first researchers to recognize that physics of ‘two-dimensional electron systems’ needs to be treated as a professional-sub-specialty. Quinn earned his Ph. D. in Physics in 1958 from the University of Maryland under the supervision of Professor R.A. Ferrell. In 1958, Quinn joined the technical staff at RCA Laboratories. Subsequently, he held visiting positions at the University of Pennsylvania and Purdue University before joining the physics faculty at Brown University in 1965. From 1965 to 1989, Quinn was at Brown University; he held the Ford Foundation Chair in Physics from 1985-1989.From 1989 to 1992, Quinn was the Chancellor of the University of Tennessee, where he has held the Willis Lincoln Chair of Excellence, Professor of Physics and Professor of Engineering Science and Mechanics, from 1992 to 2015. He is a co-author of Solid State Physics (Springer, 2009) with Kyung-Soo Yi. Quinn is a recipient of many honours, including: Fellow, American Physics Society, 1963; NATO Fellow, 1971-1972; ScD Honoris Causa, Purdue University, 1992; Outstanding Graduate Alumnus Award, Physics Department, University of Maryland, 2005; The Distinguished Alumnus Award, College of Computer, Math and Natural Sciences, University of Maryland, 2012.Shashikant B. Mulay is a Professor at the Department of Mathematics, University of Tennessee. Mulay earned his Ph.D. in Mathematics in 1982 from Purdue University under the supervision of Professor Shreeram Abhyankar. His research interests are in Algebra. He has held visiting positions at Purdue University, University of Kentucky, POSTECH (South Korea), MSRI Berkeley and the Max Plank Institute (Germany).Mark A. Shattuck is a Researcher at the Institute for Computational Science, Ton Duc Thang University in Vietnam (2017-present) and an Adjunct Assistant Professor in the Department of Mathematics, University of Tennessee (2013-present). Shattuck earned his Ph.D. in Mathematics in 2005 from the University of Tennessee under the supervision of Professor Carl Wagner. His research interests are primarily in Enumerative and Algebraic Combinatorics. He has been a Visiting Researcher at the University of Haifa (Israel) in 2011-2012 and in 2015.
