Quantum coherence, correlations and nonclassical states in the two-qubit Rabi model with parametric oscillator
V. Yogesh, Prosenjit Maity
Quantum coherence and quantum correlations are studied in the strongly interacting system composed of two qubits and an oscillator with the presence of a parametric medium. To anal…
Enhancement of squeezing in the Rabi model with parametric nonlinearity
V. Yogesh, Prosenjit Maity
The squeezing effect arises in the interacting qubit-oscillator system is studied with the presence of a parametric oscillator in the Rabi model. Based on the generalized rotating…
Study of the spin kitten states in a strongly coupled spin-oscillator system
M. Balamurugan, R. Chakrabarti, B. Virgin Jenisha +1
Utilizing an adiabatic approximation method a bipartite qudit-oscillator Hamiltonian is explicitly studied for low spin values in both strong and ultrastrong coupling regimes. The…
Evolution of the entanglement of the -type of states in a coupled two cavity system via an adiabatic approximation
R. Chakrabarti, G. Sreekumari, V. Yogesh
We study a system of two cavities each encapsulating a qubit and an oscillator degrees of freedom. An ultrastrong interaction strength between the qubit and the oscillator is assum…
Nonclassicality and decoherence of photon-added squeezed coherent Schrödinger kitten states in a Kerr medium
R. Chakrabarti, V. Yogesh
We study the nonclassicality of the evolution of a superposition of an arbitrary number of photon-added squeezed coherent Schrödinger cat states in a nonlinear Kerr medium. The non…
Evolution of a hybrid micro-macro entangled state of the qubit-oscillator system via the generalized rotating wave approximation
R. Chakrabarti, V. Yogesh
We study the evolution of the hybrid entangled states in a bipartite (ultra) strongly coupled qubit-oscillator system. Using the generalized rotating wave approximation the reduced…
