Tunable spin-orbit coupled Bose-Einstein condensates in deep optical lattices

10 Jul 2016 Salerno M. Abdullaev F. Kh. Gammal A. Tomio Lauro

Binary mixtures of Bose-Einstein condensates trapped in deep optical lattices and subjected to equal contributions of Rashba and Dresselhaus spin-orbit coupling (SOC), are investigated in the presence of a periodic time modulation of the Zeeman field. SOC tunability is explicitly demonstrated by adopting a mean-field tight-binding model for the BEC mixture and by performing an averaging approach in the strong modulation limit... (read more)
