DOI: 10.1002/andp.201700014
Abstract: A two qubits system interacting with two independent spin-environments connecting with the third environment is constructed in order to demonstrate the effect of the multi-environment for quantum correlation. In this process, the freezing phenomenon appears… read more here.

DOI: 10.1007/s10773-016-3230-5
Abstract: We study the dynamics of quantum entanglement and quantum discord between two non-interacting qubits, which couple with two independent spin baths, obeying the XXZ Hamiltonian. After the Holstein-Primakoff transformation, one could reduce the spin bath… read more here.

DOI: 10.1007/s11128-016-1451-4
Abstract: Dynamics of an open two-qubit system is investigated in the post-Markovian regime, where the environments have a short-term memory. Each qubit is coupled to separate environment which is held in its own temperature. The inter-qubit… read more here.

DOI: 10.1007/s11128-020-02967-0
Abstract: We investigate the dynamics of quantum discord in a system of three non-interacting qubits, initially entangled in a Greenberger–Horne–Zeilinger state, in the presence of mixed classical environments. Precisely, the joint impacts of a static noise… read more here.

DOI: 10.1038/s41598-021-82303-3
Abstract: In this paper we develop an approach for detecting entanglement, which is based on measuring quantum correlations and constructing a correlation matrix. The correlation matrix is then used for defining a family of parameters, named… read more here.
