Variational Approach to Many-Body Problems Incorporating Many-Body Effects at Finite Temperature
Akimitsu Kirikoshi, Wataru Kohno, Takafumi Kita
We develop a variational approach at finite temperature that incorporates many-body correlation self-consistently. The grand potential is constructed in terms of Green's function e…
Variational Wave Function for Inhomogeneous Bose--Einstein Condensate with 3/2-Body Correlations
Wataru Kohno, Akimitsu Kirikoshi, Takafumi Kita
We construct a variational wave function for inhomogeneous weakly interacting Bose--Einstein condensates beyond the mean-field approximation by incorporating -body correlation…
Ground-State Wave Function with Interactions between Different Species in -Component Miscible Bose-Einstein Condensates
Wataru Kohno, Akimitsu Kirikoshi, Takafumi Kita
We construct a variational ground-state wave function of weakly interacting M-component Bose-Einstein condensates beyond the mean-field theory by incorporating the dynamical 3/2-bo…
