Parametric instability of ultracold Bose gases with long-range interaction and quantum fluctuations trapped in optical lattices
Etienne Wamba, Jeremie Bai, A. Serge Tchakoutio Nguetcho
We investigate the dynamical instabilities of an ultracold Bose-Bose mixture with long-range dipole-dipole interactions, trapped in deep optical lattices and subject to periodicall…
Sphere on a plane: Two-dimensional scattering from a finite curved region
James R. Anglin, Etienne Wamba
Non-relativistic particles that are effectively confined to two dimensions can in general move on curved surfaces, allowing dynamical phenomena beyond what can be described with sc…
Mapping as a probe for heating suppression in periodically driven quantum many-body systems
Etienne Wamba, Axel Pelster, James R. Anglin
Experiments on periodically driven quantum systems have effectively realized quasi-Hamiltonians, in the sense of Floquet theory, that are otherwise inaccessible in static condensed…
Exact -point function mapping between pairs of experiments with Markovian open quantum systems
Etienne Wamba, Axel Pelster
We formulate an exact spacetime mapping between the -point correlation functions of two different experiments with open quantum gases. Our formalism extends a quantum-…
Exact quantum field mappings between different experiments on quantum gases
Etienne Wamba, Axel Pelster, James R. Anglin
Experiments on trapped quantum gases can probe challenging regimes of quantum many-body dynamics, where strong interactions or non-equilibrium states prevent exact solutions. Here…
Dynamical instability of a Bose-Einstein condensate with higher-order interactions in an optical potential through a variational approach
E. Wamba, S. Sabari, K. Porsezian +2
We investigate the dynamical instability of Bose-Einstein condensates (BECs) with higher-order interactions immersed in an optical lattice with weak driving harmonic potential. For…
Dynamics of matter-wave solutions of Bose-Einstein condensates in a homogeneous gravitational field
Etienne Wamba, Hermano Velten, Alidou Mohamadou +2
We find a matter-wave solution of Bose-Einstein condensates trapped in a harmonic-oscillator potential and subjected to a homogeneous gravitational field, by means of the extended…
Power spectrum for the Bose-Einstein condensate dark matter
Hermano Velten, Etienne Wamba
We assume that dark matter is composed of scalar particles that form a Bose-Einstein condensate (BEC) at some point during the cosmic evolution. Afterwards, cold dark matter is in…
