Quantum-Classical Transition of Photon-Carnot Engine Induced by Quantum Decoherence
H. T. Quan, P. Zhang, C. P. Sun
We study the physical implementation of the Photon Carnot engine (PCE) based on the cavity QED system [M. Scully et al, Science, \textbf{299}, 862 (2003)]. Here, we analyze two dec…
Antibunching effect of the radiation field in a microcavity with a mirror undergoing heavily damping oscillation
Yu-xi Liu, Chang-pu Sun
The interaction between the radiation field in a microcavity with a mirror undergoing damping oscillation is investigated. Under the heavily damping cases, the mirror variables are…
Quantum searching's underlying SU(2) structure and its quantum decoherence effects
Sixia Yu, Chang-Pu Sun
The search operation for a marked state by means of Grover's quantum searching algorithm is shown to be an element of group SU(2) which acts on a 2-dimensional space spanned by the…
Gardiner's phonon for Bose-Einstein Condensation: A physical realization of the -deformed Boson
C. P. Sun, S. X. Yu, Y. B. Gao
The Gardiner's phonon presented for a particle-number conserving approximation method to describe the dynamics of Bose-Einstein Condesation (BEC) (C.W. Gardiner, Phys. Rev. A 56, 1…
Quantum Dynamics for the Control of Atomic State by a Quantized Optical Ring Cavity
Chang-Pu Sun
A generalized approach of the Born-Oppenheimer approximation is developed to analytically deal with the influence exercised by the spatial motion of atom's mass-center on a two-lev…
Dynamical Realizability for Quantum Measurement and Factorization of Evolution Operator
Chang_Pu Sun
By building a general dynamical model for quantum measurement process,it is shown that the factorization of reduced evolution operator sufficiently results in the quantum mechanica…
