Quantum Geometry Induced Third Order Nonlinear Transport Responses
Debottam Mandal, Sanjay Sarkar, Kamal Das +1
Nonlinear transport phenomena offer an exciting probe into the band geometry and symmetry properties of a system. While most studies on nonlinear transport have looked at second-or…
Nonlinear Valley Hall Effect
Kamal Das, Koushik Ghorai, Dimitrie Culcer +1
The valley Hall effect arises from valley contrasting Berry curvature and requires inversion symmetry breaking. Here, we propose a nonlinear mechanism to generate a valley Hall cur…
Chiral anomalies in 3D spin-orbit coupled metals: electrical, thermal, and gravitational anomaly
Sunit Das, Kamal Das, Amit Agarwal
The discovery of a chiral anomaly in Weyl semimetals, the non-conservation of chiral charge and energy across two opposite chirality Weyl nodes, has sparked immense interest in und…
Observation of time-reversal symmetric Hall effect in graphene-WSe2 heterostructures at room temperature
Priya Tiwari, Divya Sahani, Atasi Chakraborty +5
In this letter, we provide experimental evidence of the time-reversal symmetric Hall effect in a mesoscopic system, namely high-mobility graphene/WSe heterostructures. This lin…
