Dynamics of a solitonic vortex in an anisotropically trapped superfluid
J. M. Gomez Llorente, J. Plata
We analytically study the dynamics of a solitonic vortex (SV) in a superfluid confined in a non-axisymmetric harmonic trap. The study provides a framework for analyzing the role of…
Expanding ring-shaped Bose-Einstein condensates as analogs of cosmological models: Analytical characterization of the inflationary dynamics
J. M. Gomez Llorente, J. Plata
We analytically study the expansion of a Bose-Einstein condensate in a ring-shaped trap with an increasing central radius. The evolution of the ground state is described using a sc…
Black-hole lasing in Bose-Einstein condensates: analysis of the role of the dynamical instabilities in a nonstationary setup
J. M. Gomez Llorente, J. Plata
We present a theoretical study on the origin of some findings of recent experiments on sonic analogs of gravitational black holes. We focus on the realization of a black-hole lasin…
Acceleration of spin-orbit coupled Bose-Einstein condensates: analytical description of the emergence of Landau-Zener transitions
J. M. Gomez Llorente, J. Plata
We analytically study the effect of gravitational and harmonic forces on ultra-cold atoms with synthetic spin-orbit coupling (SOC). In particular, we focus on the recently observed…
Periodic driving control of Raman-induced spin-orbit coupling in Bose-Einstein condensates: the heating mechanisms
J. M. Gomez Llorente, J. Plata
We focus on a technique recently implemented for controlling the magnitude of synthetic spin-orbit coupling (SOC) in ultra-cold atoms in the Raman-coupling scenario. This technique…
Coherent response of a stochastic nonlinear oscillator to a driving force: analytical characterization of the spectral signatures
J. Plata
We study the dynamics of a classical nonlinear oscillator subject to noise and driven by a sinusoidal force. In particular, we give an analytical identification of the mechanisms r…
