DC conductivity of tilted Dirac Fermions across the Lifshitz Transition: short- versus long-range impurities

Mohammad H. Pakzamir, Zahra Faraei, Ali G. Moghaddam

We theoretically investigate the DC conductivity of two-dimensional tilted Dirac systems subject to short- and long-range impurity scattering. Using the Kubo formalism, we systemat…
