Universal nonlinear responses of quantum Hall systems with Galilean invariance
Tatsuya Amitani, Yusuke Nishida
We study two-dimensional systems with Galilean invariance gapped under magnetic fields. When such quantum Hall systems are coupled with external sources for charge, energy, and mom…

Dynamical chiral magnetic current and instability in Weyl semimetals
Tatsuya Amitani, Yusuke Nishida
Weyl semimetals realize massless relativistic fermions with two Weyl nodes separated in energy and momentum space, whose low-energy physics is described by Dirac fermions with an a…
