Numerical solutions for Bose-Einstein condensates in PT symmetric double well potentials — •Daniel Haag, Dennis Dast, Holger Cartarius, and Günter Wunner — 1. Institut für Theoretische Physik, Universität Stuttgart

PT symmetry has been studied mainly within the context of mathematical physics. Recently it could be experimentally observed in an optical analogue by Rüter et. al.[1]. However it is desirable to observe PT symmetry in real quantum mechanical systems. For this purpose we investigate Bose-Einstein condensates in PT symmetric double well potentials. The PT symmetry is achieved by inducing particles to one well and extracting them from the other. We solve the nonlinear Gross-Pitaevskii equation numerically and examine the behaviour near the PT symmetry breaking.
