Nesting instability of gapless U(1) spin liquids with spinon Fermi pockets in two dimensions
Wilhelm G. F. Krüger, Lukas Janssen
Quantum spin liquids are exotic states of matter that may be realized in frustrated quantum magnets and feature fractionalized excitations and emergent gauge fields. Here, we consi…
Gross-Neveu-Heisenberg criticality from competing nematic and antiferromagnetic orders in bilayer graphene
Shouryya Ray, Lukas Janssen
We study the phase diagram of an effective model of competing nematic and antiferromagnetic orders of interacting electrons on the Bernal-stacked honeycomb bilayer, as relevant for…
Fractionalized quantum criticality in spin-orbital liquids from field theory beyond the leading order
Shouryya Ray, Bernhard Ihrig, Daniel Kruti +3
Two-dimensional spin-orbital magnets with strong exchange frustration have recently been predicted to facilitate the realization of a quantum critical point in the Gross-Neveu-SO(3…
Field-induced intermediate ordered phase and anisotropic interlayer interactions in -RuCl
Christian Balz, Lukas Janssen, Paula Lampen-Kelley +6
In -RuCl, an external magnetic field applied within the honeycomb plane can induce a transition from a magnetically ordered state to a disordered state that is potentially r…
High-field thermal transport properties of the Kitaev quantum magnet alpha-RuCl3: evidence for low-energy excitations beyond the critical field
Richard Hentrich, Xiaochen Hong, Matthias Gillig +11
We investigate the phononic in-plane longitudinal low-temperature thermal conductivity kappa_ab of the Kitaev quantum magnet alpha-RuCl3 for large in-plane magnetic fields up to 33…
Flux crystals, Majorana metals, and flat bands in exactly solvable spin-orbital liquids
Sreejith Chulliparambil, Lukas Janssen, Matthias Vojta +2
Spin-orbital liquids are quantum disordered states in systems with entangled spin and orbital degrees of freedom. We study exactly solvable spin-orbital models in two dimensions wi…
