Identifying geometric third-order nonlinear transport in disordered materials
Zhen-Hao Gong, Zhi-Hao Wei, Hai-Zhou Lu +1
In nonlinear transport, the quantum-geometric effects can generate higher-harmonic voltages in response to a driving current, which has defined a fast-moving field of intense inter…

Scaling analysis of quantum geometry in second-order nonlinear transport
Zhen-Hao Gong, Z. Z. Du, Hai-Peng Sun +2
Quantum geometry encodes the structure of the Hilbert space of Bloch states and can be accessed through nonlinear transport. Yet, disorder-induced mechanisms generically contribute…

Spinor-dominated magnetoresistance driven by the topological phase transition in -AgSe
Cheng-Long Zhang, Yilin Zhao, Yiyuan Chen +7
A topological insulator is a quantum material which possesses conducting surfaces and an insulating bulk. Despite extensive researches on the properties of Dirac surface states, th…
