Imaginary Gauge Fields for One-Way Transparency and Absorption in a Passive Metasurface
Qingdong Yang, Zhongfu Li, Xinhua Wen +3
Electromagnetic nonreciprocity enables waves to respond differently when their propagation direction is reversed, forming the basis of isolation, directional routing, and asymmetri…
Quantized decay charges in non-Hermitian networks characterized by directed graphs
Wenwen Liu, Junyao Wu, Li Zhang +6
Non-Hermitian physics has unveiled a realm of exotic phenomena absent in Hermitian systems, with the non-Hermitian skin effect (NHSE) showcasing boundary-localized eigenstates driv…
Adiabaticity violation under arbitrarily slow evolution
Oubo You, Zhaoqi Jiang, Jinhui Shi +3
The quantum adiabatic theorem, a cornerstone of quantum mechanics, asserts that a gapped quantum system remains in its instantaneous eigenstate during sufficiently slow evolution,…
Shortcuts to adiabatic non-Abelian braiding on silicon photonic chips
Wange Song, Xuanyu Liu, Jiacheng Sun +6
The non-Abelian braiding describes the exchange behavior of anyons, which can be leveraged to encode qubits for quantum computing. Recently, this concept has been realized in class…
