Proof of bulk-edge correspondence for band topology by Toeplitz algebra
Zixian Zhou, Liang-Liang Wan
We rigorously yet concisely prove the bulk-edge correspondence for general -dimensional (D) topological insulators in complex Altland-Zirnbauer classes, which states that the…
Squeezing-induced Topological Gap Opening on Bosonic Bogoliubov Excitations
Liang-Liang Wan, Zixian Zhou, Zhi-Fang Xu
We investigate the role of squeezing interaction in inducing topological Bogoliubov excitations of a bosonic system. We introduce a squeezing transformation which is capable of red…
Topological Classification of Excitations in Quadratic Bosonic Systems
Zixian Zhou, Liang-Liang Wan, Zhi-Fang Xu
We investigate the topological classification of excitations in quadratic bosonic systems with an excitation band gap. Time-reversal, charge-conjugation, and parity symmetries in b…
Protecting coherence by reservoir engineering: intense bath disturbance
Zixian Zhou, Zhiguo Lü, Hang Zheng
We put forward a scheme based on reservoir engineering to protect quantum coherence from leaking to bath, in which we intensely disturb the Lorentzian bath by N harmonic oscillator…
Quantum Zeno and anti-Zeno effects in open quantum systems
Zixian Zhou, Zhiguo Lü, Hang Zheng +1
Traditional approach on quantum Zeno effect (QZE) and quantum anti-Zeno effect (QAZE) in open quantum systems (implicitly) assumes the bath (environment) state returning to its ori…
Topology-Induced Symmetry Breaking for Vortex with Artificial Monopole
Zixian Zhou, Zhiguo Lü, Hang Zheng
We construct an artificial U(1) gauge field in the cold atom system to form a monopole along with vortices. It is supposed that the cold atoms are confined on a spherical surface,…
