Topological Optical Pseudospin Injection Beyond Weyl Semimetals
Suvendu Ghosh, Chuanchang Zeng, A. Taraphder +2
Photoinduced effects are now reckoned to be important tools to reveal a rich gamut of entrancing physics in topological materials, which are normally inaccessible to conventional p…
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…

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…

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…

Chuanchang Zeng, Xiao-Qin Yu, Zhi-Ming Yu +1
Topological insulators (TIs) hold promise as a platform for spintronics applications due to the fascinating spin-momentum locking (SML) of the surface states. One particular intere…

Chuanchang Zeng, Gargee Sharma, Tudor D. Stanescu +1
We discuss the feasibility of measurement-based braiding in semiconductor-superconductor (SM-SC) heterostructures in the so-called quasi-Majorana regime the topologically-trivi…
Majorana versus Andreev bound state energy oscillations in a 1D semiconductor-superconductor heterostructure
