Tuning insulator-semimetal transitions in 3D topological insulator thin films by inter-surface hybridization and in-plane magnetic fields
Yang Xu, Guodong Jiang, Ireneusz Miotkowski +2
A pair of Dirac points (analogous to a vortex-antivortex pair) associated with opposite topological numbers (with Berry phases) can be merged together through parameter tuni…

Geometric response of quantum Hall states to electric fields
YingKang Chen, Guodong Jiang, Rudro R. Biswas
Exploiting novel aspects of the quantum geometry of charged particles in a magnetic field via gauge-invariant variables, we provide tangible connections between the response of qua…

Connection topology of step edge state bands at the surface of a three dimensional topological insulator
Yishuai Xu, Guodong Jiang, Janet Chiu +5
Topological insulators in the BiSe family manifest helical Dirac surface states that span the topologically ordered bulk band gap. Recent scanning tunneling microscopy meas…
