Topological phases of a generalised tripartite Haldane model
Ahmed Al-kharusi, Alessandro Principi, Niels R. Walet
We present a generalised tripartite Haldane model with a complex nearest neighbour hopping parameter. The total magnetic flux through the primitive unit cell, which consists of thr…
Non-Fermi-liquid behaviour of electrons coupled to gauge phonons
Rutvij Gholap, Alexey Ermakov, Alexander Kazantsev +3
We identify overdamped gauge phonons as a new microscopic route to non-Fermi-liquid behaviour in Dirac materials. These phonons couple to electronic currents rather than densities,…
Nonconserved Density Accumulations in Orbital Hall Transport: Insights from Linear Response Theory
Hao Sun, Alexander Kazantsev, Alessandro Principi +1
We present a linear response theory for stationary density accumulations in anomalous transport phenomena, such as the orbital Hall effect, where the transported density is odd und…
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…
Optical conductivity and damping of plasmons due to electron-electron interaction
Prachi Sharma, Alessandro Principi, Giovanni Vignale +1
We re-visit the issue of plasmon damping due to electron-electron interaction. The plasmon linewidth can related to the imaginary part of the charge susceptibility or, equivalently…
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…
