Zero-Field Surface Charge Due to the Gap Suppression in -Wave Superconductors
Ezekiel Sambo Joshua, Hikaru Ueki, Wataru Kohno +1
We perform a microscopic study on the redistribution of electric charge near the surface of a model -wave superconductor cut along the [110] direction, with a Fermi surface appr…
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…
Number-Phase Fluctuations in Isolated Superconductors
Xiaotian Si, Wataru Kohno, Takafumi Kita
We improve the Bardeen-Cooper-Schrieffer wave function with a fixed particle number so as to incorporate many-body correlations beyond the mean-field treatment. It is shown that th…
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…
Hall Effect in the Vortex Lattice of d-Wave Superconductors with Anisotropic Fermi surfaces
Wataru Kohno, Hikaru Ueki, Takafumi Kita
On the basis of the augmented quasiclassical theory of superconductivity with the Lorentz force, we study the mag- netic field dependence of the charge distribution due to the Lore…
