We present a method to calculate an upper bound on the generation of entanglement in any
spin system using the Fannes-Audenaert inequality for the von Neumann entropy. Our …

We study spin squeezing, an intrinsic quantum property, in the Dicke model without the
rotating-wave approximation. We show that the spin squeezing can reveal the underlying …

We analyze numerically the dynamical generation of quantum entanglement in a system of
two interacting particles, started in a coherent separable state, for decreasing values of ℏ. As …

Schroedinger equation on a Hilbert space H, represents a linear Hamiltonian dynamical
system on the space of quantum pure states, the projective Hilbert space PH. Separable …

We analyze the connections between the dynamical generation of continuous variable
entanglement and the underlying classical trajectories in pairs of coupled oscillators. In the …

We study spin squeezing, an intrinsically quantum property, in the quantum kicked top
model exhibiting chaotic behaviours in the classical limit. We show that spin squeezing can …

Motivated by recent developments in quantum entanglement, we study the relations among
concurrence and phase entropy of a three-level atom interacting with a bimodal cavity field …

In this paper, we consider two spins initially prepared in a product of coherent states and
study their entanglement dynamics due to a general interacting Hamiltonian. We adopt an …

We used quantum Fisher information (QFI) to distinguish quantum chaotic and regular
dynamics in Dicke model. The QFI, which reflects the geometric properties of a state in …
