Putting initially all atoms in m_F=0 component we find that the system evolves into the state...
We study the energetic and dynamic stability of coreless vortices in nonrotated spin-1 Bose-Einstein condensates, trapped with a three-dimensional optical potential and a Ioffe-Pritchard field. The stability of stationary vortex states is investigated by solving the corresponding Bogoliubov equations. ...

We present calculations of the fully quantum-mechanical spin evolution for a single spatial mode of an F = 1 antiferromagnetic spinor Bose-Einstein condensate in the presence of time-dependent microwave dressing. We focus on the coherent spin evolution driven by spin-exchange collisions, where two...
We propose a scheme to generate and detect quantum coherence and quantum entanglement in a spin-1 Bose-Einstein condensate with the help of spin squeezing parameter and quantum Fisher information. It is shown that quantum coherence and quantum entanglement are independent of the Rabi frequency and ...

We propose a novel type of composite light-matter magnetometer based on a transversely driven multi-component Bose-Einstein condensate coupled to two distinct electromagnetic modes of a linear cavity. Above the critical pump strength, the change of the population imbalance of the condensate caused by...
