An explicitly solvable NLS model with discontinuous standing waves
Riccardo Adami, Filippo Boni, Takaaki Nakamura +1
We study the NLS Equation on the line with a point interaction given by the superposition of an attractive delta potential with a dipole interaction, in the cases of -subcriti…
Discontinuous Ground States for NLSE on with a Fülöp-Tsutsui interaction
Riccardo Adami, Takaaki Nakamura, Alice Ruighi
We analyse the existence and the stability of the ground states of the one-dimensional nonlinear Schrödinger equation with a focusing power nonlinearity and a defect located at the…
Generating nonequilibrium stationary state from ground state condensate through an almost-adiabatic cycle
Atushi Tanaka, Takaaki Nakamura, Taksu Cheon
It is shown that the ground state of weakly interacting Bose particles in a quasi one-dimensional box trap can be converted into an excited stationary state by an adiabatic cyclic…
Spectral properties of nonlinear Schrödinger equation on a ring
Takaaki Nakamura, Taksu Cheon
The stationary states of nonlinear Schr{ö}dinger equation on a ring with a defect is numerically analyzed. Unconventional connection conditions are imposed on the point defect, and…
