Strain-Induced Tuning of Third-Harmonic Generation in Monolayer Black Phosphorene
Yan Meng, Kainan Chang, Wei Song +3
Based on the tight-binding model and the semiconductor Bloch equations, this work systematically reveals the microscopic mechanism of strain engineering in turning of third-harmoni…
Gate Voltage Tunable Second Harmonic Generation in Mono- and Bi-layer Black Phosphene
Yan Meng, Kainan Chang, Yanyan Qian +2
Black phosphorene (BP) has emerged as a promising platform for tunable nonlinear photonics due to its layer-dependent bandgap, high carrier mobility, and remarkable in-plane anisot…
Harmonic generation of graphene quantum dots in Hartree-Fock approximation
Kainan Chang, Ying Song, Yuwei Shan +1
We theoretically investigate harmonic generation in graphene quantum dots under linearly polarized optical pulses, focusing on excitonic effects. Combining the tight-binding model…
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…
Theory of Optical Activity in Doped Systems with Application to Twisted Bilayer Graphene
K. Chang, Z. Zheng, J. E. Sipe +1
We theoretically study the optical activity in a doped system and derive the optical activity tensor from a light wavevector-dependent linear optical conductivity. Although the lig…
