Logarithmic Gross-Pitaevskii equation [PDF]

open access: yes, 2022
31 pagesWe consider the Schrödinger equation with a logarithmic nonlinearty and non-trivial boundary conditions at infinity. We prove that the Cauchy problem is globally well posed in the energy space, which turns out to correspond to the energy space ...

Semiclassical Spectral Series Localized on a Curve for the Gross–Pitaevskii Equation with a Nonlocal Interaction [PDF]

open access: yes, 2021
We propose the approach to constructing semiclassical spectral series for the generalized multidimensional stationary Gross–Pitaevskii equation with a nonlocal interaction term.

Comparison of Splitting Methods for Deterministic/Stochastic Gross–Pitaevskii Equation

open access: yesMathematical and Computational Applications, 2019
In this paper, we discuss the different splitting approaches to numerically solvethe Gross–Pitaevskii equation (GPE). The models are motivated from spinor Bose–Einsteincondensate (BEC).

Nonlinear quantum search using the Gross–Pitaevskii equation

open access: yesNew Journal of Physics, 2013
We solve the unstructured search problem in constant time by computing with a physically motivated nonlinearity of the Gross–Pitaevskii type. This speedup comes, however, at the novel expense of increasing the time-measurement precision.

Turbulence in the two-dimensional Fourier-truncated Gross–Pitaevskii equation

open access: yesNew Journal of Physics, 2013
We undertake a systematic, direct numerical simulation of the two-dimensional, Fourier-truncated, Gross–Pitaevskii equation to study the turbulent evolutions of its solutions for a variety of initial conditions and a wide range of parameters.

Vortex helices for the Gross-Pitaevskii equation [PDF]

open access: yes, 2005
International audienceWe prove the existence of travelling vortex helices to the Gross-Pitaevskii equation in R^3. These solutions have an infi nite energy, are periodic in the direction of the axis of the helix and have a degree one at infinity in the ...

Dilute dipolar quantum droplets beyond the extended Gross-Pitaevskii equation

open access: yesPhysical Review Research, 2019
Dipolar quantum droplets are exotic quantum objects that are self-bound due to the subtle balance of attraction, repulsion, and quantum correlations. Here we present a systematic study of the critical atom number of these self-bound droplets, comparing ...

q-Deformed Gross Pitaevskii Equation [PDF]

open access: yes, 2023
We derive the Gross Pitaevskii equation (GPE) for condensate of bosons obeying deformed statistics under external potential and inter-particle interaction. First, we obtain the well-known Schrodinger equation.

Resonant Solutions to Gross-Pitaevskii Equation With Periodic Potential [PDF]

open access: yes, 2022
Over the years, many methods have been used for solving the Gross-Pitaevskii equation which is also known as a nonlinear Schrodinger equation. In this thesis, we study a nonlinear polyharmonic equation with a periodic potential and quasi-periodic ...
