The phase diagrams of periodically driven spin–orbit coupled 87Rb and 23Na Bose–Einstein condensates (BECs) are visually distinct from undriven systems. In article number 2000194, Zhi Lin demonstrates two distinguishing features of these systems. A series of quantum tricritical points emerge quasi‐periodically from 87Rb BECs, while the existence of stripe phase in a suitable parameter region is found...
The phase boundaries of periodically driven spin–orbit coupled BECs with effective two‐body interactions are analytically calculated by using variational method. The phase diagrams of periodically driven and systems present distinguished features from undriven systems, respectively. For the BECs, the critical density (density at quantum tricritical point) will be dramatically reduced...
