Parametric resonance of a Bose-Einstein condensate in a ring trap with periodically driven interactions

28 Apr 2018 Zhu Chen-Xi Yi Wei Guo Guang-Can Zhou Zheng-Wei

We study the instability of a ring Bose-Einstein condensate under a periodic modulation of inter-atomic interactions. The condensate exhibits temporal and spatial patterns induced by the parametric resonance, which can be characterized by Bogoliubov quasi-particle excitations in the Floquet basis... (read more)
