Valley-Controlled Viscosity of Two-Dimensional Dirac Fluids
Alexey Ermakov, Alessandro Principi
Motivated by recent experiments in weakly hybridized small-angle twisted bilayer graphene, we investigate how valley imbalance affects the viscosity of two-dimensional Dirac fluids…
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…
The role of polarization field terms in a model for a cavity quantum material
Arwen Lloyd, Adam Stokes, Alessandro Principi +1
Constructing models for cavity quantum materials requires a careful treatment of the light-matter coupling. In general, one must specify matrix elements constructed from the materi…
Spin and Charge Transport Mediated by Fractionalized Excitations
Alexey Ermakov, Alessandro Principi
We study charge and spin transport in systems composed of itinerant electrons and localized magnetic moments of a Kitaev quantum spin liquid (QSL) phase. For example, $α-{\rm RuCl}…
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…
Extreme electron-hole drag and negative mobility in the Dirac plasma of graphene
L. A. Ponomarenko, Alessandro Principi, A. D. Niblett +13
Coulomb drag between adjacent electron and hole gases has attracted considerable attention, being studied in various two-dimensional systems, including semiconductor and graphene h…
