Between Mott and cluster Mott: spin-orbit entangled dimer singlets in BaCeRuO

L. Pätzold, A. Sandberg, H. Schilling +8

The hexagonal 4d ruthenates Ba3MRu2O9 host structural dimers and exhibit a delicate balance of competing interactions. Hund's coupling, trigonal crystal-field splitting, and hoppin…

Spin fractionalization at the edge of quantum Hall fluids induced by bulk quasiparticles

Alexander Fagerlund, Alberto Nardin, Leonardo Mazza +1

We define a measurable spin for the edge of a lowest Landau level and incompressible fractional quantum Hall state in the presence of an Abelian or non-Abelian bulk quasiparticle.…

Parafermions in Moiré Minibands

Hui Liu, Raul Perea-Causin, Emil J. Bergholtz

Moiré materials provide a remarkably tunable platform for topological and strongly correlated quantum phases of matter. Very recently, the first zero field Abelian fractional Chern…

Non-Abelian Fractional Chern Insulators and Competing States in Flat Moiré Bands

Hui Liu, Zhao Liu, Emil J. Bergholtz

Breakthrough experiments have recently realized fractional Chern insulators (FCIs) in moiré materials. However, all states observed are Abelian, the possible existence of more exot…

Paired fermions in strong magnetic fields and daughters of even-denominator Hall plateaus

Misha Yutushui, Maria Hermanns, David F. Mross

Recent quantum Hall experiments have observed `daughter states' next to several plateaus at half-integer filling factors in various platforms. These states were first proposed base…

Stacking of charge-density waves in 2H-NbSe bilayers

Fabrizio Cossu, Dhani Nafday, Krisztian Palotás +4

We employ ab-initio electronic structure calculations to investigate the charge-density waves and periodic lattice distortions in bilayer 2H-NbSe. We demonstrate that the verti…
