Competing magnetic orders and multipolar Weyl fermions in 227 pyrochlore iridates
Konstantinos Ladovrechis, Tobias Meng, Bitan Roy
Owing to comparably strong spin-orbit coupling and Hubbard interaction, iridium based 227 pyrochlore oxides harbor a rich confluence of competing magnetic orders and emergent multi…
Universal Hall conductance scaling in non-Hermitian Chern insulators
Solofo Groenendijk, Thomas L. Schmidt, Tobias Meng
We investigate the Hall conductance of a two-dimensional Chern insulator coupled to an environment causing gain and loss. Introducing a biorthogonal linear response theory, we show…
Origin of the quasi-quantized Hall effect in ZrTe5
Stanislaw Galeski, Toni Ehmcke, Rafal Wawrzynczak +24
The quantum Hall effect (QHE) is traditionally considered a purely two-dimensional (2D) phenomenon. Recently, a three-dimensional (3D) version of the QHE has been reported in the D…
Bosonization in 2+1 dimensions via Chern-Simons bosonic particle-vortex duality
Oguz Turker, Jeroen van den Brink, Tobias Meng +1
Dualities provide deep insight into physics by relating two seemingly distinct theories. Here we consider a duality between lattice fermions and bosons in (2+1) spacetime dimension…
Pseudo field effects in type II Weyl semimetals: new probes for over tilted cones
Daniel Sabsovich, Tobias Meng, Dmitry I. Pikulin +2
We study the effects of pseudo-magnetic fields on Weyl semimetals with over-tilted Weyl cones, or type II cones. We compare the phenomenology of the resulting pseudo-Landau levels…
