Phase Space Methods for Degenerate Quantum Gases

Bryan J. Dalton, John Jeffers, and Stephen M. Barnett

Abstract

Recent experimental progress has enabled cold atomic gases to be studied at nanokelvin temperatures, creating new states of matter where quantum degeneracy occurs—Bose–Einstein condensates and degenerate Fermi gases. Such quantum states are of macroscopic dimensions. As its title suggests, this book presents the phase space theory approach to treating the physics of degenerate quantum gases, an approach already widely used in quantum optics. However, degenerate quantum gases involve massive bosonic and fermionic atoms, not massless photons. The book begins with a review of Fock states for syst ... More

Keywords: boson, fermion, identical massive particles, mode, field, distribution function, quantum correlation function, Fokker–Planck equation, Langevin stochastic equation, Grassmann algebra, Grassmann calculus
