Ashok Chatterjee

Ashok Chatterjee received his M.S. degree from Calcutta University, India, carried out his doctoral work on “large-N expansions” at IACS, Kolkata, India, and received his Ph.D. degree from Jadavpur University, Kolkata, in 1988. He worked as a Visiting Postdoctoral Fellow at S. N. Bose National Centre for Basic Sciences, Kolkata, for about a year and a half, and then joined the University of Hyderabad, India, as a Lecturer in 1990, where he became a Full Professor in 2001. He has worked in several areas of condensed matter physics which include electron-phonon interactions; polarons and bipolarons; low-dimensional systems; many-body theory; nonclassical behavior; thermal expansions and their applications to phase transitions in metals, alloys, magnetic materials, glasses, minerals, and superconductors; strongly correlated Fermi systems; Holstein-Hubbard model; Luttinger liquid; and high Tc-superconductivity. Presently, he is also interested in quantum diffusion, dissipation, localization, and spintronics. He received the Satya Murthy Award of Indian Physics Association for 1992, for his contributions to large-N expansion and its applications to solid -state physics. He has visited several places for scientific collaboration. In 2001, he visited Ankara University as a Consultant under the United Nations International Short-Term Advisory Resources Program of Scientific and Technical Research Council of Turkey. He visited ISSP, University of Tokyo, Japan, for one year during 2001–2002 as a Foreign Research Fellow under the Centre of Excellence programme of Japan and the Max-Planck Institute for Physics of Complex Systems, Dresden, Germany, as a Guest Scientist in 2003, and Bilkent University as a Visiting Professor for two years (2006–2008). Presently, he is a Visiting Professor at the University of Alberta, Edmonton. He is also a Member of the Editorial Board of International Journal of Modern Physics B, Modern Physics Letters B, Research Leters in Physics, and Open Condensed Matter Physics Journal.
