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…
Intermode-coupling modulation in the fermion-boson model: heating effects in the BCS regime
J. Plata
Heating induced by an oscillating modulation of the interaction strength in an atomic Fermion pair condensate is analyzed. The coupled fermion-boson model, generalized by incorpora…
Feshbach molecule formation through an oscillating magnetic field: subharmonic resonances
S. Brouard, J. Plata
The conversion of ultracold atoms to molecules via a magnetic Feshbach resonance with a sinusoidal modulation of the field is studied. Different practical realizations of this meth…
