N. P. Proukakis is a Professor of Quantum Physics at Newcastle University and the Associate Director of the Joint Quantum Centre Durham-Newcastle. He is an expert on finite temperature non-equilibrium modelling of quantum gases, and his research interests span from atomic physics to optical condensates, being mainly focused on universal features, non-equilibrium dynamics, multi-component condensates and superfluid turbulence. D. W. Snoke is a Professor of Physics at the University of Pittsburgh and a Fellow of the American Physical Society. He is author of over 130 articles and 4 books, including Bose-Einstein Condensation (with A. Griffin and S. Stringari, Cambridge, 1995), one of the first books to survey the phenomenon. His research focuses on non-equilibrium dynamics, semiconductor optics and Bose-Einstein condensation. P. B. Littlewood is Professor of Physics at the University of Chicago, former Head of the Cavendish Laboratory, University of Cambridge and former Director of Argonne National Laboratory, Illinois. Author of more than 200 articles, he has played an important role in the theory of Bose-Einstein condensation in cold atoms, polaritons and excitonic systems.
