Robust spin-polarized midgap states at step edges of topological crystalline insulators
Paolo Sessi, Domenico Di Sante, Andrzej Szczerbakow +11
Topological crystalline insulators are materials in which the crystalline symmetry leads to topologically protected surface states with a chiral spin texture, rendering them potent…
Topological quantum properties of chiral crystals
Guoqing Chang, Benjamin J. Wieder, Frank Schindler +10
Chiral crystals are materials whose lattice structure has a well-defined handedness due to the lack of inversion, mirror, or other roto-inversion symmetries. These crystals represe…
Topological Quantum Liquids with Long-Range Couplings
Kristian Patrick, Titus Neupert, Jiannis K. Pachos
Very few topological systems with long-range couplings have been considered so far due to our lack of analytic approaches. Here we extend the Kitaev chain, a 1D quantum liquid, to…
Hallmarks of Hund's coupling in the Mott insulator CaRuO
D. Sutter, C. G. Fatuzzo, S. Moser +22
A paradigmatic case of multi-band Mott physics including spin-orbit and Hund's coupling is realised in CaRuO. Progress in understanding the nature of this Mott insulating p…
Density wave instabilities and surface state evolution in interacting Weyl semimetals
Manuel Laubach, Christian Platt, Ronny Thomale +2
We investigate the interplay of many-body and band structure effects of interacting Weyl semimetals (WSM). Attractive and repulsive Hubbard interactions are studied within a model…
No-Go Theorem for Boson Condensation in Topologically Ordered Quantum Liquids
Titus Neupert, Huan He, Curt von Keyserlingk +2
Certain phase transitions between topological quantum field theories (TQFT) are driven by the condensation of bosonic anyons. However, as bosons in a TQFT are themselves nontrivial…
