Fractionalized Superconductivity Mediated by Majorana Fermions in the Kitaev-Kondo Lattice
Matthew Bunney, Urban F. P. Seifert, Stephan Rachel +1
Superconductivity usually emerges from a metallic normal state which follows the Fermi-liquid paradigm. If, in contrast, the normal state is a fractionalized non-Fermi liquid, then…
Bond disorder in extended Heisenberg-Kitaev models: Spin textures and in-gap states in the high-field regime
Georgia Fragkopoulou, Matthias Vojta
We study the effect of bond disorder in extended Heisenberg-Kitaev models on the honeycomb lattice, relevant for materials such as -RuCl, in the semiclassical limit using a…
Discrete JT gravity as an Ising model
Johanna Erdmenger, Jonathan Karl, Yanick Thurn +2
Inspired by the program of discrete holography, we show that Jackiw-Teitelboim (JT) gravity on a hyperbolic tiling of Euclidean AdS gives rise to an Ising model on the dual lat…
Critical properties of metallic and deconfined quantum phase transitions in Dirac systems
Zi Hong Liu, Matthias Vojta, Fakher F. Assaad +1
We characterize, by means of large-scale fermion quantum Monte Carlo simulations, metallic and deconfined quantum phase transitions in a bilayer honeycomb model in terms of their q…
A Classical Chiral Spin-Liquid from Chiral Interactions on the Pyrochlore Lattice
Daniel Lozano-Gómez, Yasir Iqbal, Matthias Vojta
Classical spin-liquids are paramagnetic phases which feature nontrivial patterns of spin correlations within their ground-state manifold whose degeneracy scales with system size. O…
SU() altermagnetism: Lattice models, magnon modes, and flavor-split bands
Pedro M. Cônsoli, Matthias Vojta
Altermagnetism, a type of magnetic order that combines properties of ferro- and antiferromagnets, has stirred great interest lately not only as a promising source of spintronics ap…
