Brownian motion theory of the two-dimensional quantum vortex gas
Hiroshi Kuratsuji
A theory of Brownian motion is presented for an assembly of vortices. The attempt is motivated by a realization of Dyson' Coulomb gas in the context of quantum condensates. By star…
Domain wall dynamics in the spinor Bose-Einstein condensates
Hiroshi Kuratsuji
A dynamical theory is presented for the domain wall in the spinor Bose-Einstein condensate of "effective"one-dimension. The formulation is based on the time-dependent Landau-Ginzbu…
Evolution of the Stokes parameters, polarization singularities, and optical skyrmion
Hiroshi Kuratsuji, Satoshi Tsuchida
A physical theory is presented for polarized light from an aspect of polarization singularity.This is carried out by analyzing the evolution equation of the Stokes parameters that…
Random motion theory of an optical vortex in nonlinear birefringent media
Satoshi Tsuchida, Hiroshi Kuratsuji
A theoretical study is presented for the random aspect of an optical vortex inherent in the nonlinear birefringent Kerr effect, which is called the optical spin vortex. We start wi…
Superconducting fluctuation current in a space with the Kerr metric
Hiroshi Kuratsuji, Satoshi Tsuchida
We study a fluctuation current through a superconducting ring placed in a space with the Kerr metric. This attempt aims at exploring conceptual problem; namely, we are concerned wi…
Stochastic theory of polarized light in nonlinear birefringent media: An application to optical rotation
Satoshi Tsuchida, Hiroshi Kuratsuji
A stochastic theory is developed for the light transmitting the optical media exhibiting linear and nonlinear birefringence. The starting point is the two--component nonlinear Schr…
