A. Ravi. P. Rau is a Professor of Physics at Louisiana State University who conducts theoretical studies in atomic and molecular physics. He has held visiting faculty positions at Yale, the Raman Research Institute, Bangalore, India, the Tata Institute of Fundamental Research, Bombay, India, the Australian National University, Camberra, and the University of Freiberg, German. he was also a Visiting Fellow at the Joint Institute for Laboratory Astrophysics, Boulder, Co, in 1984. He is a Fellow of the American Physical Society and wa awarded the K. S. Krishman Gold Medal from the University of Delhi.
His recent interest is in the area of quantum information: studies of entanglement and other correlations such as quantum discord, their evolution under dissipative and decoherent processes and how they may be controlled, geometrical and symmetry studies of operators and states of N qubits and connections betweem the Lie and clifford algebras involved with topics in projective geometry and design theory.
