Heisenberg-limited metrology with perturbing interactions
Chao Yin, Andrew Lucas
We show that it is possible to perform Heisenberg-limited metrology on GHZ-like states, in the presence of generic spatially local, possibly strong interactions during the measurem…
Prethermal quasiconserved observables in Floquet quantum systems
Chao Yin, Pai Peng, Xiaoyang Huang +2
Prethermalization, by introducing emergent quasiconserved observables, plays a crucial role in protecting Floquet many-body phases over exponentially long time, while the ultimate…
Bound on quantum scrambling with all-to-all interactions
Chao Yin, Andrew Lucas
We prove bounds on operator growth and infinite temperature out-of-time-ordered correlators in many-body systems with spin- degrees of freedom which interact via t…
Observation of Floquet prethermalization in dipolar spin chains
Pai Peng, Chao Yin, Xiaoyang Huang +2
Periodically driven Floquet quantum systems provide a promising platform to investigate novel physics out of equilibrium. Unfortunately, the drive generically heats up the system t…
Wannier basis method for KAM effect in quantum mechanics
Chao Yin, Yu Chen, Biao Wu
The effect of Kolmogorov-Arnold-Moser (KAM) theorem in quantum systems is manifested in dividing eigenstates into regular and irregular states. We propose an effective method based…
