Quantum Chaos and Regularity in Ultracold Fermi Gases
arXiv:0709.1900 · doi:10.1103/PhysRevE.76.057204
Abstract
Quantum fluctuation of the energy is studied for an ultracold gas of interacting fermions trapped in a three-dimensional potential. Periodic-orbit theory is explored, and energy fluctuations are studied versus particle number for generic regular and chaotic systems, as well for a system defined by a harmonic confinement potential. Temperature effects on the energy fluctuations are investigated.
