Bound states and decay dynamics in -level Friedrichs model with factorizable interactions

Jia-Ming Zhang, Yu Xin, Bing Chen

Considering an -level system interacting factorizably with a continuous spectrum, we derive expressions for the bound states and the dynamical evolution within this single-excit…

Presence of the negative pressure in the quantum vacuum

Zhentao Zhang

We investigate the microscopic origin of the negative pressure produced by the constant energy density of the vacuum. It is shown that the zero-point photons in the quantum vacuum…

Tangential Casimir force in the misaligned system: Magnetic media, real conductors, and a torque

Zhentao Zhang

Uncharged parallel plates in the misaligned system can experience a tangential Casimir force between them. We consider the role of magnetic response in this effect by extending the…

An impurity-induced gap system as a quantum data bus for quantum state transfer

Bing Chen, Yong Li, Z. Song +1

We introduce a tight-binding chain with a single impurity to act as a quantum data bus for perfect quantum state transfer. Our proposal is based on the weak coupling limit of the t…

Quantum phase transition of two-mode Bose-Einstein condensates with an entanglement order parameter

Wei Fan, Yan Xu. Bing Chen, Zhaoyang Chen +2

The ground state entanglement of the two-mode Bose-Einstein condensate is investigated through a quantum phase transition approach. The entanglement measure is taken as the order p…

Quantum corrections to the dynamics of the Bose-Einstein condensate in a double-well potential

Wei Fan, Yan Xu, Bing Chen

The dynamics of the Bose-Einstein condensate (BEC) in a double-well potential is of- ten investigated under the mean-field theory (MFT). This works successfully for large particle…
