- TITLE
- [GS_C_MS] Nonlinear Hall effect from long-lived, valley-polarizing relaxons
- ABSTRACT
- Normally, carrier transport is hindered by the scattering of charge carriers. In this presentation, I will show that some transport phenomenon can be assisted by carrier scattering. I will explain the conventional Berry-curvature dipole picture of non-linear Hall effect [1,2] and show that the real physics is qualitatively different from this naive picture [3].
