Third-order Hall effect in the surface states of a topological insulator
Tanay Nag, Sanjib Kumar Das, Chuanchang Zeng +1
Time reversal and inversion symmetric materials fail to yield linear and nonlinear responses since they possess net zero Berry curvature. However, higher-order Hall response can be…
Probing electron-hole weights of an Andreev bound state by transient currents
Zhan Cao, Gu Zhang, Hao Zhang +4
Andreev bound states (ABSs) are localized quantum states that contain both electron and hole components. They ubiquitously reside in inhomogeneous superconducting systems. Followin…
Quantum oscillations of the nonlinear planar effects signifying chiral anomaly in Weyl Semimetals
Chuanchang Zeng, Snehasish Nandy, Pu Liu +2
In view of searching the signature of the celebrated chiral anomaly (CA) in Weyl semimetals (WSMs) in ongoing experiments, quantum oscillation in linear response regime has been co…
Low-Frequency Divergence of Circular Photomagnetic Effect in Topological Semimetals
Jin Cao, Chuanchang Zeng, Xiao-Ping Li +4
Novel fermions with relativistic linear dispersion can emerge as low-energy excitations in topological semimetal materials. Here, we show that the orbital moment contribution in th…
