Gross-Neveu-Heisenberg criticality from expansion
Konstantinos Ladovrechis, Shouryya Ray, Tobias Meng +1
The Gross-Neveu-Heisenberg universality class describes a continuous quantum phase transition between a Dirac semimetal and an antiferromagnetic insulator. Such quantum critical po…
Steering Majorana braiding via skyrmion-vortex pairs: a scalable platform
Jonas Nothhelfer, Sebastián A. Díaz, Stephan Kessler +4
Majorana zero modes are quasiparticles that hold promise as building blocks for topological quantum computing. However, the litmus test for their detection, the observation of exot…
Propagation of longitudinal acoustic phonons in ZrTe exposed to a quantizing magnetic field
Toni Ehmcke, Stanislaw Galeski, Denis Gorbunov +4
The compound ZrTe has recently been connected to a charge-density-wave (CDW) state with intriguing transport properties. Here, we investigate quantum oscillations in ultrasound…
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…
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…
An exactly soluble model for a fractionalized Weyl semimetal
Fabian Hotz, Apoorv Tiwari, Oguz Turker +4
We construct an exactly solvable lattice model of a fractional Weyl semimetal (FWS). The low energy theory of this strongly interacting state is that of a Weyl semimetal built out…
