Pseudogauge field driven acoustoelectric current in two-dimensional hexagonal Dirac materials
Pankaj Bhalla, Giovanni Vignale, Habib Rostami
Using a diagrammatic scheme, we study the acoustoelectric effects in two-dimensional (2D) hexagonal Dirac materials due to the sound-induced pseudo-gauge field. We analyze both uni…
Unidirectional magneto-transport of linearly dispersing topological edge states
Zhanning Wang, Pankaj Bhalla, Mark Edmonds +2
Quantum spin-Hall edges are envisaged as next-generation transistors, yet they exhibit dissipationless transport only over short distances. Here we show that in a diffusive sample,…
Quantum geometry induced second harmonic generation
Pankaj Bhalla, Kamal Das, Dimitrie Culcer +1
Quantum geometry of the electron wave function plays a significant role in the linear and non-linear responses of crystalline materials. Here, we study quantum geometry induced sec…
Non-linear ballistic response of quantum spin-Hall edge states
Pankaj Bhalla, Ming-Xun Deng, Rui-Qiang Wang +2
Topological edge states exhibit dissipationless transport and electrically-driven topological phase transitions, making them ideal for next-generation transistors that are not cons…
Optical phonon contribution to the thermal conductivity of a quantum paraelectric
Pankaj Bhalla, Nabyendu Das
Motivated by recent experimental findings, we study the contribution of a quantum critical optical phonon branch to the thermal conductivity of a paraelectric system. We consider t…
