Topological magnon noises
Shuang Liang, Tengyue Zhao, Yu-Hang Li +1
We develop a comprehensive formalism for magnon transport in ferromagnetic insulators driven by a temperature gradient. The formulas for magnon current and corresponding magnon noi…
Superconducting triode effect in a quantum-dot Josephson junction with a biased top gate
Yu-Hang Li, Xiaan Du, Hua Jiang +1
Non-reciprocal supercurrents enable non-dissipative rectification, holding great promise for superconducting electronics. Conventionally, this non-reciprocity, termed the supercond…
Topological multicomponent superconductivity with sizable -wave admixture in twisted bilayer cuprates
Yu-Hang Li, Congjun Wu, Wang Yang
We investigate multicomponent superconductivity in twisted bilayer cuprates with order parameter , where is the symmetric layer-resolved…
Emergent giant topological Hall effect in twisted Fe3GeTe2 metallic system
Hyuncheol Kim, Kai-Xuan Zhang, Yu-Hang Li +3
The topological Hall effect, driven by the exchange interaction between conduction electrons and topological magnetic textures such as skyrmions, is a powerful probe for investigat…
Three-dimensional quantum anomalous Hall effect in Weyl semimetals
Zhi-Qiang Zhang, Yu-Hang Li, Ming Lu +4
The quantum anomalous Hall effect (QAHE) is a quantum phenomenon in which a two-dimensional system exhibits a quantized Hall resistance in the absence of magnetic field, wh…
Tri-component-pairing chiral superconductivity on the honeycomb lattice with mixed - and -wave symmetries
Yu-Hang Li, Jiarui Jiao, Xiao-Xiao Zhang +2
In this work, we investigate chiral topological superconductors on a two-dimensional honeycomb lattice with coexisting , , and -wave pairing symmetries. Usi…
