Spin and density self-ordering in dynamic polarization gradients fields
Natalia Masalaeva, Wolfgang Niedenzu, Farokh Mivehvar +1
We study the zero-temperature quantum phase diagram for a two-component Bose-Einstein condensate in an optical cavity. The two atomic spin states are Raman coupled by two transvers…

Cavity-assisted squeezing and entanglement: Non-adiabatic effects and optimal cavity-atomic ensemble matching
N. I. Masalaeva, A. N. Vetlugin, I. V. Sokolov
We investigate theoretically quantum entanglement of light with the collective spin polarization of a cold atomic ensemble in cavity-assisted Raman schemes. Previous works concentr…

Cavity-assisted atomic Raman memories beyond the bad cavity limit: effect of four-wave mixing
N. G. Veselkova, N. I. Masalaeva, I. V. Sokolov
Quantum memories can be used not only for the storage of quantum information, but also for substantial manipulation of ensembles of quantum states. Therefore, the speed of such man…
