We present and distribute a parallel finite-element toolbox written in the free software
FreeFEM for computing the Bogoliubov-de Gennes (BdG) spectrum of stationary solutions to …

We present a finite element toolbox for the computation of Bogoliubov-de Gennes modes
used to assess the linear stability of stationary solutions of the Gross-Pitaevskii (GP) …

Close to the superfluid plane-wave (PW)–supersolid stripe (ST) phase transition point of a
zero-temperature quasi-one-dimensional spin-orbit-coupled Bose gas, we find that an …

Considering both interspecies and intraspecies quantum fluctuations in quasi-one
dimensional ultracold Bose–Bose mixtures, we show that new LHY-like effects lead to …

We study the collective excitation spectrum of a Raman-induced spin-orbit-coupled spin-1
Bose-Einstein condensates confined in a quasi-one-dimensional harmonic trap while …

The ultracold atoms are an ideal platform to implement atomtronics and Josephson junctions
analogous to superconducting circuits. The collective modes of a Bose gas split by a …

We present a theoretical study of the collective excitations of the supersolid annular stripe
phase of a spin-orbital-angular-momentum-coupled (SOAM-coupled) spin-1 Bose-Einstein …

Our investigation focuses on the condensate density, excited and condensed fractions of
bosons in a mixture of two-component segregated weakly interacting Bose–Einstein …

Motivated by the recent experiments [Chen et al., Phys. Rev. Lett 121, 113204 (2018), Chen
et al., Phys. Rev. Lett. 121, 250401 (2018)], we investigate the low-lying excitation spectrum …
