Rydberg assisted light shift imbalance induced blockade in an atomic ensemble ,

In particular, we show that when all excitation fields are classical, there is no blockade. In Section 5, we show how the interaction between two Rydberg states can be used to ...

Spin squeezing and quantum correlations
... We have classified spin states into two mutually exclusive classes, namely, oriented and non-oriented states, and studied their squeezing properties. It is clear from our analysis that squeezing is exhibited only by non-oriented states. Considering in particular the nonoriented states of a spin-1 sy ...
