A BOSEEINSTEIN CONDENSATE WITH PTSYMMETRIC DOUBLEDELTA FUNCTION LOSS AND GAIN IN A HARMONIC TRAP: A TEST OF RIGOROUS ESTIMATES

Author: Haag , Daniel; Cartarius , Holger; Wunner , Günter
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)

We consider the linear and nonlinear Schrödinger equation for a Bose-Einstein condensate in a harmonic trap with PT-symmetric double-delta function loss and gain terms. We verify that the conditions for the applicability ...
Stationary and Dynamical Solutions of the GrossPitaevskii Equation for a BoseEinstein Condensate in a PT symmetric Double Well

Author: Cartarius , Holger; Dast , Dennis; Haag , Daniel; Wunner , Günter; Eichler , Rüdiger; Main , Jorg
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)

We investigate the Gross-Pitaevskii equation for a Bose-Einstein condensate in a PT symmetric double-well potential by means of the time-dependent variational principle and numerically exact solutions. A one-dimensional ...
