Anomalous thermoelectric Hall response of interacting 2D Dirac fermions
A. Daria Dumitriu-I., Feng Liu, Alexander E. Kazantsev +1
We study the anomalous thermoelectric Hall response of two-dimensional massive Dirac fermions to first order in the electron-electron interaction. We compute both the Nernst respon…
Broken Lorentz symmetry and violation of the Wiedemann-Franz law in topological insulators
Feng Liu, A. Daria Dumitriu-I., Alessandro Principi
We study a two-dimensional topological insulator in the presence of a static non-uniform gravitational field, which mimics the variations in the temperature distribution. We derive…
No bulk thermal currents in massive Dirac fermions
Feng Liu, A. Daria Dumitriu-I., Alessandro Principi
We calculate the energy current flowing in the bulk of a (2+1)-dimensional system of massive Dirac fermions and along a (1+1)-dimensional domain wall generated by flipping the sign…
First-order effect of electron-electron interactions on the anomalous Hall conductivity of massive Dirac fermions
A. Daria Dumitriu-I., Darius-A. Deaconu, Alexander E. Kazantsev +1
We investigate the first-order correction to the anomalous Hall conductivity of 2D massive Dirac fermions arising from electron-electron interactions. In a fully gapped system in t…
