摘要：Recently, the proposal of the remnant effects of Lorentz symmetry and CPT breaking in nonrelativistic Quantum Mechanics has been investigated in the presence of the non-minimal couplings. Such a possibility opens up the way to study new type of phase generation and we can investigate the influences of this background on a variety of phase transitions. In the present work, we propose to reasses the Bose-Einstein Condensates (BEC) starting from a relativistic theory with non-minimal coupling to a Lorentz and CPT breaking background to compute its non-relativistic limit and study the contribution of the background to the Gross-Pitevskii equation for the BEC. The non-minimal coupling is the one that generates an Aharonov-Casher phase, motivated by the fact that we would like to study circular states in this system.
