Generalized Thomas–Fermi equations as the Lampariello class of Emden–Fowler equations
(Elsevier Science BV, 2017)
Formation of vortices in a dense Bose-Einstein condensate
(AMER PHYSICAL SOC, 2008)
A relaxation method is employed to study a rotating dense Bose-Einstein condensate beyond the Thomas-Fermi approximation. We use a slave-boson model to describe the strongly interacting condensate and derive a generalized ...
Modelo de Hubbard extendido para fermiones con tres grados de libertad internos
(Bogotá - Ciencias - Maestría en Ciencias - FísicaDepartamento de FísicaUniversidad Nacional de Colombia - Sede Bogotá, 2019-04-20)
En la presente tesis se considera fermiones con tres grados de libertad internos en una dimensión, sistema que puede ser descritos por un modelo de Fermi-Hubbard SU(3), al cual se adiciona un término de interacción a ...
Fluid-dynamical scheme for equilibrium properties of two trapped fermion species with pairing interactions
(American Physical Society, 2008-10)
We present a generalization of the fluid-dynamical scheme developed for nuclear physics to the case of two trapped fermion species with pairing interactions. To establish a macroscopic description of the mass and momentum ...
Two-mode effective interaction in a double-well condensate
(American Physical Society, 2013-05)
We investigate the origin of a disagreement between the two-mode model and the exact GrossPitaevskii dynamics applied to double-well systems. In general this model, even in its improved version, predicts a faster dynamics ...
