Bose-Einstein condensation in frustrated optical lattices — •Ludwig Mathey1, Peter Janzen1, and Wen-Min Huang2 — 1ZOQ/ILP, Universität Hamburg, Hamburg, Germany — 2National Chung-Hsing University, Taichung, Taiwan
We explore the critical behavior of Bose-Einstein condensation in frustrated lattices. In these lattices, an additional, chiral symmetry emerges, which is spontaneously broken at low temperatures. We discuss how this broken symmetry has been experimentally detected via interference of two independent chiral condensates. Furthermore, we present the critical behavior of these systems that are obtained within a renormalization group approach.
