Thermal quantum discord in the anisotropic Heisenberg XXZ model with the Dzyaloshinskii-Moriya interaction
quantum discord Dzyaloshinskii-Moriya anisotropic Heisenberg XXZ
2010/3/10
The thermal quantum discord (QD) is studied in a two-qubit Heisenberg XXZ system with Dzyaloshinskii-Moriya (DM) interaction. We compare the thermal QD with thermal entanglement in this system and fin...
Non-thermal Hawking radiation from the Kerr black hole
black hole Hawking radiation Damour-Ruffini method quantum theory
2009/8/14
We present a short and direct derivation of Hawking radiation by using the Damour-Ruffini method, as taking into account the self-gravitational interaction from the Kerr black hole. It is found that t...
A framework for the investigation of disordered quantum systems in thermal equilibrium is proposed. The approach is based on a dynamical model--which consists of a combination of a double-bracket grad...
Dynamics of entanglement in Two-Qubit Open System Interacting with a Squeezed Thermal Bath via Dissipative interaction
Dynamics of entanglement Two-Qubit Open System Squeezed Thermal Bath Dissipative interaction
2010/4/7
We study the dynamics of entanglement in a two-qubit system interacting with a squeezed thermal bath via a dissipative system-reservoir interaction with the system and reservoir assumed to be in a sep...
