One of the appealing features of topological systems is the presence of robust edge modes.Under a sudden quantum quench,the edge modes survive for a characteristic time that scales with the system size,during which th...

Considering the influences of collective dephasing, multilocal qutrit-flip, local qutrit-flip, and the combination of global mixed noise, we study the dynamics of entanglement and the phenomenon of distillability of s...
We report the sudden appearance of distillability between two statistically independent reservoirs modelled as qutrit-qutrit systems. This feature of bipartite quantum systems is different from the previously observed...

We investigate the dynamics of quantum discord for a two-qubit system coupled to a spin chain with three-site interaction in the weak-coupling region.For the case of the initial two-qubit pure state,the decay of quant...

We study the quantum discord dynamics of a bipartite composite system in the presence of a dissipative environment and investigate the effect of the interaction between the two subsystems.The results show that the int...

Dynamics of the nonlocality measured by the violation of Svetlichny's Bell-type inequality is investigated in the non-Markovian model.The phenomenon of nonlocality sudden birth for the atoms and the reservoirs is obta...

The physical implication of a sudden jump of the Hartree-Fock solution is studied by means of a solvable model,where not only such jump occurs but also the phase transition(PT)of a many-particle system can be demonstr...
