Quantum kinetic theory of quadratic responses
M. Mehraeen
Abstract
A recurring research theme in linear response theory is the attempt to reconcile semiclassical and quantum transport. Starting from the quantum Liouville equation for the disorder-averaged density operator, this work presents a comprehensive theory of nonlinear responses in the presence of an electrostatic interaction and disorder. In addition to generalizing the equations of motion of carrier dynamics, several unexplored scattering and conductivity channels are uncovered, revealing the rich interplay between quantum geometry and disorder in the nonlinear response regime.
