Energy Spectra of Quantum Turbulence: Large-scale Simulation and Modeling
Narimasa Sasa, Takuma Kano, Masahiko Machida +3
In simulation of quantum turbulence within the Gross-Pitaevskii equation we demonstrate that the large scale motions have a classical Kolmogorov-1941 energy spectrum E(k)…
Three-dimensional dynamics of vortex lattice formation in Bose-Einstein condensates
Kenichi Kasamatsu, Masahiko Machida, Narimasa Sasa +1
We numerically study the dynamics of vortex lattice formation in a rotating cigar-shaped Bose-Einstein condensate. The study is a three-dimensional simulation of the Gross-Pitaevsk…
N Soliton Solutions to The Bogoyavlenskii-Schiff Equation and A Quest for The Soliton Solution in (3 + 1) Dimensions
Yu. S. J, K. Toda, N. Sasa +1
We study the integrable systems in higher dimensions which can be written not by the Hirota's bilinear form but by the trilinear form. We explicitly discuss about the Bogoyavlenski…
Bilinearization of a Generalized Derivative Nonlinear Schrödinger equation
Saburo Kakei, Narimasa Sasa, Junkichi Satsuma
A generalized derivative nonlinear Schrödinger equation, \ii q_t + q_{xx} + 2\ii γ|q|^2 q_x + 2\ii (γ-1)q^2 q^*_x + (γ-1)(γ-2)|q|^4 q = 0 , is studied by means of Hirota's bilinear…
