The Gross–Pitaevskii Equation for an Infinite Square Well with a Delta-Function Barrier

RJ Ragan, AR Sakhel, WJ Mullin - Journal of Low Temperature Physics, 2024 - Springer
Abstract The Gross–Pitaevskii equation is solved by analytic methods for an external double-
well potential, that is, an infinite square well plus a δ-function central barrier. We find …

Accuracy of the Gross–Pitaevskii Equation in a Double-Well Potential

AR Sakhel, RJ Ragan, WJ Mullin - Journal of Low Temperature Physics, 2024 - Springer
Abstract The Gross–Pitaevskii equation (GPE) in a double-well potential produces solutions
that break the symmetry of the underlying non-interacting Hamiltonian, ie, asymmetric …
