Emergent Surface Kondo Flat Band Driven by Competing Interactions in a Topological Ferromagnet
Nazar Zaremba, Susmita Changdar, Haojie Guo +28
A central goal of modern condensed matter physics is to uncover new quantum states of matter arising from the intertwined effects of strong electron correlations, magnetism, and ba…
Crystallographic imperfections and exotic superconductivity of UBe
Andreas Leithe-Jasper, Markus König, Yusei Shimizu +16
The symmetry of the superconducting gap is related to the symmetry of the crystal structure. In unconventional superconductors, big changes of the critical temperature, critical fi…
Disorder effects in spiral spin liquids: Long-range spin textures, Friedel-like oscillations, and spiral spin glasses
Pedro M. Cônsoli, Matthias Vojta
Spiral spin liquids are correlated states of matter in which a frustrated magnetic system evades order by fluctuating between a set of (nearly) degenerate spin spirals. Here, we in…
Partial magnetic order in kagome spin ice
Eric C. Andrade, Matthias Vojta
Motivated by the observation of partial magnetic order in kagome-based magnets, we study the classical kagome Ising antiferromagnet, known as kagome spin ice, including further-nei…
Kondo screening and coherence in kagome local-moment metals: Energy scales of heavy fermions in the presence of flat bands
Christos Kourris, Matthias Vojta
The formation of a heavy Fermi liquid in metals with local moments is characterized by multiple energy and temperature scales, most prominently the Kondo temperature and the cohere…
Nodal semimetals in to sharp pseudo-Landau levels by dimensional reduction
Fabian Köhler, Matthias Vojta
Non-uniform strain applied to graphene's honeycomb lattice can induce pseudo-Landau levels in the single-particle spectrum. Various generalizations have been put forward, including…
