Floquet theorem for open systems and its applications
C. M. Dai, Z. C. Shi, X. X. Yi
For a closed system with periodic driving, Floquet theorem tells that the time evolution operator can be written as with …
The Dynamical Invariant of Open Quantum System
S. L. Wu, X. Y. Zhang, X. X. Yi
The dynamical invariant, whose expectation value is constant, is generalized to open quantum system. The evolution equation of dynamical invariant (the dynamical invariant conditio…
Engineering the coupling between Majorana bound states
Z. C. Shi, X. Q. Shao, Y. Xia +1
We study the coupling between Majorana bound states (CMBS), which is mediated by a topologically trivial chain in the presence of pairing coupling and long-range coupling. The resu…
Robust state transfer with high fidelity in spin-1/2 chains by Lyapunov control
Z. C. Shi, X. L. Zhao, X. X. Yi
Based on the Lyapunov control, we present a scheme to realize state transfer with high fidelity by only modulating the boundary spins in a quantum spin-1/2 chain. Recall that the c…
Quantum response theory for open systems and its application to Hall conductance
H. Z. Shen, M. Qin, Y. H. Zhou +2
Quantum linear response theory considers only the response of a closed quantum system to a perturbation up to first order in the perturbation. This theory breaks down when the syst…
Non-Markovianity and memory effects in quantum open systems
S. C. Hou, S. L. Liang, X. X. Yi
Although a number of measures for quantum non-Markovianity have been proposed recently, it is still an open question whether these measures directly characterize the memory effect…
