Nonextensive Gross Pitaevskii Equation

International Journal of Geometric Methods in Modern Physics, 2023
In this paper, we consider the generalization of Gross Pitaevskii equation for condensate of bosons with nonextensive statistics. First, we use the non-additive methods and formalism to obtain the well-known Schrödinger equation. Using a suitable Hamiltonian for condensate phase and minimizing the free energy of the system by non-additive formalism, we

Conserved Gross–Pitaevskii equations with a parabolic potential

Communications in Theoretical Physics, 2022
Abstract An integrable Gross–Pitaevskii equation with a parabolic potential is presented where particle density ∣u∣2 is conserved. We also present an integrable vector Gross–Pitaevskii system with a parabolic potential, where the total particle density

Rotons and the gross-pitaevskii equation

Physics Letters A, 1980
Abstract With a plausible assumption for ψ( r ), a bubble-solution of the GP-equation in the three-dimensional case is obtained. The relation between a roton and a “bubble” is examined. The roton spectrum is derived in order to test the suggested theory of condensate wavefunctions.

Accurate Numerical Eigenstates of the Gross-Pitaevskii Equation

2020
We consider a bosonic gas of N bosons. Hartree-Fock approximation allows for a product wave function of single particle solutions \({\Psi (\vec {x_i})}\) $$\displaystyle \Psi (x_1, x_2, \cdots , x_N) = \prod _i^N \Psi (\vec {x}_i) $$ Using a pseudo-potential to account for the condensate self-interaction, the Hamiltonian is found to be ...

On the quantum Gross-Pitaevskii equation

2016
Gegenstand dieser Dissertation ist die Entwicklung neuer variationeller Algorithmen zur Untersuchung von stark korrelierten eindimensionalen Quantenfeldtheorien. Zu diesem Zweck wird das Dirac-Frenkel zeitabhaengige Variationsprinzip auf die Klasse der kontinuierlichen Matrix Produkt Zustaende (cMPS) angewandt.
