Preparation of topological modes by Lyapunov control
Z. C. Shi, X. L. Zhao, X. X. Yi
By Lyapunov control, we present a proposal to drive quasi-particles into a topological mode in quantum systems described by a quadratic Hamiltonian. The merit of this control is th…
Preparation of edge states by shaking boundaries
Z. C. Shi, S. C. Hou, L. C. Wang +1
Preparing topological states of quantum matter, such as edge states, is one of the most important directions in condensed matter physics. In this work, we present a proposal to pre…
Exact non-Markovian master equation for a driven damped two-level system
H. Z. Shen, M. Qin, Xiao-Ming Xiu +1
Driven two-level system is a useful model to describe many quantum objects, particularly in quantum information processing. However, the exact master equation for such a system is…
Quantum optical diode with semiconductor microcavities
H. Z. Shen, Y. H. Zhou, X. X. Yi
The semiconductor diode, which acts as an electrical rectifier and allows unidirectional electronic transports, is the key to information processing in integrated circuits. Analogo…
Hall conductance and topological invariant for open systems
H. Z. Shen, W. Wang, X. X. Yi
The Hall conductivity given by the Kubo formula is a linear response of the quantum transverse transport to a weak electric field. It has been intensively studied for a quantum sys…
Single-Photon Storing in Coupled Non-Markovian Atom-Cavity System
H. Z. Shen, M. Qin, X. X. Yi
Taking the non-Markovian effect into account, we study how to store a single photon of arbitrary temporal shape in a single atom coupled to an optical cavity. Our model applies to…
