Spin squeezing and Quantum Fisher Information in the Jaynes-Cummings Dicke Model
Aranya B Bhattacherjee, Deepti Sharma
We investigate spin squeezing (SS) and the quantum Fisher information (QFI) for the Jaynes-Cummings Dicke (JC-Dicke) model in a two component atomic Bose-Einstein condensate (BEC)…

Heisenberg Operator Approach for Spin Squeezing Dynamics
Aranya B. Bhattacherjee, Deepti Sharma, Axel Pelster
We reconsider the one-axis twisting Hamiltonian, which is commonly used for generating spin squeezing, and treat its dynamics within the Heisenberg operator approach. To this end w…
