Symmetry Breaking in Bose-Einstein Condensates Confined by a Funnel Potential
Bruno M. Miranda, Mateus C. P. dos Santos, Wesley B. Cardoso
In this work, we consider a Bose-Einstein condensate in the self-focusing regime, confined transversely by a funnel-like potential and axially by a double-well potential formed by…
Spontaneous symmetry breaking induced by interaction in linearly coupled binary Bose Einstein condensates
Mateus C. P. dos Santos, Wesley B. Cardoso
We analyze the spontaneous symmetry breaking (SSB) induced by one specific component of a linearly coupled binary Bose-Einstein condensate (BEC). The model is based on linearly cou…
Nonclassical properties and Anderson localization of quantum states in coupled waveguides
Thais L. Silva, Wesley B. Cardoso, Ardiley T. Avelar +1
We consider the propagation of light beams through disordered lattices of coupled waveguides searching for Anderson localization and investigating the evolution of nonclassical pro…
Linear semi-infinite programming approach for entanglement quantification
Thiago Mureebe Carrijo, Wesley Bueno Cardoso, Ardiley Torres Avelar
We explore the dual problem of the convex roof construction by identifying it as a linear semi-infinite programming (LSIP) problem. Using the LSIP theory, we show the absence of a…
Double-layer Bose-Einstein condensates: A quantum phase transition in the transverse direction, and reduction to two dimensions
Mateus C. P. dos Santos, Boris A. Malomed, Wesley B. Cardoso
We revisit the problem of the reduction of the three-dimensional (3D) dynamics of Bose-Einstein condensates, under the action of strong confinement in one direction (), to a 2D…
Quasi-one-dimensional approximation for Bose-Einstein condensates transversely trapped by a funnel potential
Mateus C. P. dos Santos, Boris A. Malomed, Wesley B. Cardoso
Starting from the standard three-dimensional (3D) Gross-Pitaevskii equation (GPE) and using a variational approximation, we derive an effective one-dimensional nonpolynomial Schröd…
