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…
Ordered phases and superconductivity in two-dimensional electron systems subject to pair spin-orbit interaction
Feng Liu, Alessandro Principi
Pair spin-orbit interaction can emerge in strongly-interacting systems characterized by a large spin-orbit coupling. Here we study the role of this interaction in stabilizing order…
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…
