Second Harmonic Generation in Topological Insulators under Quantizing Magnetic Fields
Kainan Chang, Muhammad Zubair, Jin Luo Cheng +1
We theoretically investigate the second harmonic generation (SHG) of topological insulator surface states in a perpendicular magnetic field. Our theory is based on the microscopic…
