%0 Journal Article %T Broken gauge symmetry in a Bose gas with constant particle number %A Alexej Schelle %J Physics %D 2014 %I arXiv %X The existence of broken gauge symmetries in Bose-Einstein condensates is still controversially discussed in science, since it would not conserve the total number of particles. Here, it is shown for the first time that non-random condensate and non-condensate phase distributions may arise from local particle number breaking in a Bose gas with constant particle number, while the global U(1)-gauge symmetry of the system is preserved due to particle number conservation. %U http://arxiv.org/abs/1410.7058v4
