Bose-Fermi Mixtures in One Dimension
Kunal K. Das
We analyze the phase stability and the response of a mixture of bosons and spin-polarized fermions in one dimension (1D). Unlike in 3D, phase separation happens for low fermion den…
Interference of a thermal Tonks gas on a ring
Kunal K. Das, M. D. Girardeau, E. M. Wright
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…
Crossover from one to three dimensions for a gas of hard-core bosons
Kunal K. Das, M. D. Girardeau, E. M. Wright
We develop a variational theory of the crossover from the one-dimensional (1D) regime to the 3D regime for ultra-cold Bose gases in thin waveguides. Within the 1D regime we map out…
Theory of a one-dimensional double-X atom interferometer
Marvin D. Girardeau, Kunal K. Das, Ewan M. Wright
The dynamics of an atom waveguide X-junction beam splitter becomes truly 1D in a regime of low temperatures and densities and large positive scattering lengths where the transverse…
Interference of a Tonks-Girardeau Gas on a Ring
Kunal K. Das, G. John Lapeyre, Ewan M. Wright
We study the quantum dynamics of a one-dimensional gas of impenetrable bosons on a ring, and investigate the interference that results when an initially trapped gas localized on on…
