Reduction of thermodynamic uncertainty by a virtual qubit
Yang Li, Fu-Lin Zhang
The thermodynamic uncertainty relation (TUR) imposes a fundamental constraint between current fluctuations and entropy production, providing a refined formulation of the second law…
Arbitrary Control of Non-Hermitian Skin Modes via Disorder and An Electric Field
Zhao-Fan Cai, Yang Li, Yu-Ran Zhang +4
The non-Hermitian skin effect (NHSE), characterized by the accumulation of a macroscopic number of bulk states at system boundaries, is a hallmark of non-Hermitian physics. However…
Distinguish the Orientation of Sliding Ferroelectricity by Second-Harmonic Generation
Fengfeng Ye, Qiankun Li, Zhuocheng Lu +5
As the emerging ferroelectric (FE) materials, the ultrathin two-dimensional (2D) sliding ferroelectrics without phase-matching bottleneck, usually exhibit the pronounced second har…
Dissipation and Interaction-Controlled Non-Hermitian Skin Effects
Yang Li, Zhao-Fan Cai, Tao Liu +1
Non-Hermitian skin effects (NHSEs) have recently been extensively studied at the single-particle level. When many-body interactions become dominant, novel non-Hermitian phenomena c…
The origin of strings and rings in the atomic dynamics of disordered systems
Omar Hussein, Yang Li, Y. Mishin
It has long been believed that the atomic dynamics in disordered structures, such as undercooled liquids and pre-melted interfaces, are characterized by collective atomic rearrange…
