A short review of recent developments of the Dicke model in quantum optics is presented.
The focus is on the model in a cavity at zero temperature and in the rotating wave …

Knowledge of the dynamical behavior of correlations with no classical counterpart, like
entanglement, nonlocal correlations and quantum discord, in open quantum systems is of …

In this paper, we study how to preserve entanglement and nonlocality under dephasing
produced by classical noise with large low-frequency components, such as 1/f noise, using …

It is well known that the violation of Bell's inequality in the form given by Clauser, Horne,
Shimony, and Holt (CHSH) in two-qubit systems requires entanglement, but not vice versa …

We explore the bipartite non-classical correlations of two quantum wells coupled to two
spatially separated microcavities. The microcavities are filled by linear optical media and …

Amplitude damping changes entangled pure states into usually less-entangled mixed states.
We show, however, that even local amplitude damping of one or two qubits can result in …

In this paper, some non-classical correlations are investigated for bipartite partitions of two
qubits trapped in two spatially separated cavities connected by an optical fiber. The results …

We consider two entangled qubits, each of which is coupled to its own reservoir, so that their
entanglement degrades with time. To enhance the qubits' entanglement at a time during the …

In this paper, we explore the dynamics of nonlocal correlations in a two-qubit system, that is,
first prepared in a Gisin state and then interacts with a bosonic non-Markovian environment …

The uncertainty principle imposes constraints on an observer's ability to make precision
measurements for two incompatible observables; thus, uncertainty relations play a key role …
