Enhanced Photon Squeezing in Two-Photon Dicke Model
Priyankar Banerjee, Deepti Sharma, Aranya B Bhattacherjee
We explore the phenomena of quadrature squeezing of photons in the Two-Photon Dicke Model under the mean-field approximation in the thermodynamic limit. The strength of photon sque…
Power-law growth of time and strength of squeezing near quantum critical point
Deepti Sharma, Brijesh Kumar
The dynamics of squeezing across quantum phase transition in two basic models, viz., the one-axis twisting model in transverse field and the Dicke model, is investigated using Hols…
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…
