Linear Entropy of a Driven Central Spin Interacting with an Antiferromagnetic Environment

Linear Entropy of a Driven Central Spin Interacting with an Antiferromagnetic Environment
We exploit a scheme to obtain a long-lived entanglement using a driven central spin interacting with an antiferromagnetic spin bath. Our numerical results show the effects of different parameters on the population inversion and the entanglement dynamics in terms of the linear entropy. It is shown that the long-lived entanglement is an intriguing result corresponding to the collapse region of ... Read more

Entanglement in the Bimodal Jaynes–Cummings Model with the Two-Mode Squeezed Vacuum State

Entanglement in the Bimodal Jaynes–Cummings Model with the Two-Mode Squeezed Vacuum State
In this paper, we study the interaction between the two-level atom and a bimodal cavity field, namely, two-mode Jaynes–Cummings model when the atom and the modes are initially in the atomic superposition state and two-mode squeezed vacuum state, respectively. For this system we investigate the atomic inversion, linear entropy and atomic Wehrl entropy. We show that there is a connection ... Read more
