DOI: 10.1016/j.physa.2019.121344
Abstract: Abstract The dynamical stability properties of gap solitons in a quasi-one-dimensional Bose–Einstein Condensate (BEC) loaded in a Jacobian elliptic sine potential are investigated numerically. The Gross–Pitaevskii equation (GPE) is adopted to describe the dynamical behaviors… read more here.

DOI: 10.1103/physrevd.104.103505
Abstract: We study models of non-minimally coupled relativistic fluid and k-essence scalar field in the background of a flat Friedmann-Lemaitre-Robertson-Walker universe. The non-minimal coupling term is introduced in the Lagrangian level. We employ the variational approach… read more here.

DOI: 10.1140/epjc/s10052-020-8273-3
Abstract: The dynamical stability of massive thin shells with a given equation of state (EOS) (both for the barotropic and non-barotropic case) is here compared with the results coming from thermodynamical stability. Our results show that… read more here.
