Observing parity-time symmetry in diffusive systems
Pei-Chao Cao, Ran Ju, Dong Wang +6
Phase modulation has scarcely been mentioned in diffusive systems since the diffusion process does not carry momentum like waves. Recently, the non-Hermitian physics provides a new…
Observation of Non-Hermitian Skin Effect in Thermal Diffusion
Yun-Kai Liu, Pei-Chao Cao, Minghong Qi +4
The paradigm shift of the Hermitian systems into the non-Hermitian regime profoundly modifies the inherent topological property, leading to various unprecedented effects such as th…
Demonstration of acoustic high-order Stiefel-Whitney semimetal in bilayer graphene sonic crystals
Xiao Xiang, Xiang Ni, Feng Gao +4
Recently, higher-order topological phases have endowed materials many exotic topological phases. For three-dimensional (3D) higher-order topologies, it hosts topologically protecte…
Chiral and non-chiral swift mode conversion near an exception point with dynamic adiabaticity engineering
Dong Wang, Wen-Xi Huang, Bo Zhou +7
The eigenvalue of a non-Hermitian Hamiltonian often forms a self-intersecting Riemann surface, leading to a unique mode conversion phenomenon when the Hamiltonian evolves along cer…
Loss compensation and super-resolution with excitations at complex frequencies
Seunghwi Kim, Yu-Gui Peng, Simon Yves +1
Abbe diffraction limit fundamentally bounds the resolution of conventional optical imaging and spectroscopic systems. Along the years, several schemes have been introduced to overc…
