lattice gauge theories with matter fields
Kaustubh Roy, Elio J. König
Motivated by the exotic phenomenology of certain quantum materials and recent advances in programmable quantum emulators, we here study fermions and bosons in lattice…
Interaction-induced velocity renormalization in magic angle twisted trilayer graphene
Laura Classen, J. H. Pixley, Elio J. König
Twistronics heterostructures provide a novel route to control the electronic single particle velocity and thereby to engineer strong effective interactions. Here we show that the r…
Kerr effect from diffractive skew scattering in chiral superconductors
Elio J. König, Alex Levchenko
We calculate the temperature dependent anomalous ac Hall conductance for a two-dimensional chiral p-wave superconductor. This quantity determines the polar Kerr effect,…
Half-integer quantum Hall effect of disordered Dirac fermions at a topological insulator surface
E. J. König, P. M. Ostrovsky, I. V. Protopopov +3
The unconventional (half-integer) quantum Hall effect for a single species of Dirac fermions is analyzed. We discuss possible experimental measurements of the half-integer Hall con…
Density of states in a two-dimensional chiral metal with vacancies
P. M. Ostrovsky, I. V. Protopopov, E. J. König +3
We study quantum interference effects in a two-dimensional chiral metal (bipartite lattice) with vacancies. We demonstrate that randomly distributed vacancies constitute a peculiar…
