Quantum Brayton cycle with coupled systems as working substance
X. L. Huang, L. C. Wang, X. X. Yi
We explore the quantum version of Brayton cycle with a composite system as the working substance. The actual Brayton cycle consists of two adiabatic and two isobaric processes. Two…
Non-Markovian Effects on the Geometric Phase
X. L. Huang, X. X. Yi
The geometric phases of a two-level atom interacting with non-Markovian environments are calculated and the non-Markovian effects on the geometric phases are discussed in this pape…
Effective Hamiltonian Approach to Open Systems and Its Applications
X. L. Huang, X. X. Yi, Chunfeng Wu +3
By using the effective Hamiltonian approach, we present a self-consistent framework for the analysis of geometric phases and dynamically stable decoherence-free subspaces in open s…
Non-Markovian Quantum Jump with Generalized Lindblad Master Equation
X. L. Huang, H. Y. Sun, X. X. Yi
The Monte Carlo wave function method or the quantum trajectory/jump approach is a powerful tool to study dissipative dynamics governed by the Markovian master equation, in particul…
Effect of feedback on the control of a two-level dissipative quantum system
L. C. Wang, X. L. Huang, X. X. Yi
We show that it is possible to modify the stationary state by a feedback control in a two-level dissipative quantum system. Based on the geometric control theory, we also analyze t…
Loschmidt echo and Berry phase around degeneracies in nonlinear systems
X. X. Yi, X. L. Huang, W. Wang
We study the Loschmidt echo and Berry phase in a nonlinear system transported around a double and triple degeneracy. The nonlinearity of the system makes the Berry phase different…
