Parametric excitations in a harmonically trapped binary Bose-Einstein condensate
Meiling Wang, Juan Wang, Yan Li +2
We investigate parametric excitation and pattern formation in a harmonically trapped two-component Bose-Einstein condensate. We assume the condensate to be in the miscible phase, b…

Adjusting exceptional points using saturable nonlinearities
Qingxin Gu, Chunlei Qu, Yongping Zhang
We study the impact of saturable nonlinearity on the presence and location of exceptional points in a non-Hermitian dimer system. The inclusion of the saturable nonlinearity leads…
