Floquet topological properties in the Non-Hermitian long-range system with complex hopping amplitudes
Gang-Feng Guo, Yan Wang, Xi-Xi Bao +1
Non-equilibrium phases of matter have attracted much attention in recent years, among which the Floquet phase is a hot point. In this work, based on the Periodic driving Non-Hermit…

Quantum Fluctuation-Response Inequality and Its Application in Quantum Hypothesis Testing
Yan Wang
We establish a general quantum fluctuation-response inequality that bounds the difference in expectation values of an observable between two quantum states via the quantum relative…
