Phys. Rev. Lett. 89, 170404 (2002) [4 pages]Interference of a Thermal Tonks Gas on a RingReceived 28 May 2002; published 8 October 2002 A nonzero temperature generalization of the Fermi-Bose mapping theorem is used to study the exact quantum statistical dynamics of a one-dimensional gas of impenetrable bosons on a ring. We investigate the interference produced when an initially trapped gas localized on one side of the ring is released, split via an optical-dipole grating, and recombined on the other side of the ring. Nonzero temperature is shown not to be a limitation to obtaining high visibility fringes. © 2002 The American Physical Society URL:
