Comparative studies of many-body corrections to an interacting Bose condensate
Shohei Watabe, Yoji Ohashi
We compare many-body theories describing fluctuation corrections to the mean-field theory in a weakly interacting Bose-condensed gas. Using a generalized random-phase approximation…

Stability Criterion for Superfluidity based on the Density Spectral Function
Shohei Watabe, Yusuke Kato
We study a stability criterion hypothesis for superfluids in terms of the the local density spectral function applicable both to homogeneous and inhomogeneous systems.…
