A Pfaffian quantum Hall state of ultracold bosons
Joyce Kwan, Perrin Segura, Yanfei Li +7
Fractional quantum Hall states are a cornerstone of topological physics, hosting fractionally charged quasiparticles with exotic statistics that promise to enable topologically pro…

Momentum-Space Entanglement Signatures and Spinon Breakdown in the - Zig-Zag Heisenberg Chain
Tom Oeffner, Ludwig Bordfeldt, Andreas Feuerpfeil +5
We investigate the resilience of spinon quasiparticles in the - zig-zag spin chain () from the viewpoint of momentum-space entanglement. For small , we show t…

Chiral Gapless Spin Liquid in Hyperbolic Space
Felix Dusel, Tobias Hofmann, Atanu Maity +5
We analyze the Kitaev model on the hyperbolic lattice. The is formed by a regular tricoordinated tiling of nonagons, where the 3-color coding of bonds according…
