Double-passage ground-state cooling induced by quantum interference in the hybrid optomechanical system
Lingchao Li, Longjiang Liu, Shuo Zhang +2
We propose a quantum interference cooling scheme for a nano-mechanical resonator (NAMR) in a hybrid optomechanical system, where the atoms are trapped in an optomechanical cavity,…

Completely positive maps within the framework of direct-sum decomposition of state space
Longjiang Liu, D. M. Tong
We investigate completely positive maps for an open system interacting with its environment. The families of the initial states for which the reduced dynamics can be described by a…

Separable states and the geometric phases of an interacting two-spin system
C. W. Niu, G. F. Xu, Longjiang Liu +3
It is known that an interacting bipartite system evolves as an entangled state in general, even if it is initially in a separable state. Due to the entanglement of the state, the g…
