Theory of weak symmetry breaking of translations in topologically ordered states and its relation to topological superconductivity from an exact lattice charge-flux attachment
Peng Rao, Inti Sodemann
We study topologically ordered states enriched by translational symmetry by employing a recently developed 2D bosonization approach that implements an exact $\mathbb…
Anatomy of Z2 fluxes in anyon Fermi liquids and Bose condensates
Oscar Pozo, Peng Rao, Chuan Chen +1
We study in detail the properties of pi-fluxes embedded in a state with a finite density of anyons that form either a Fermi liquid or a Bose-Einstein condensate. By employing a rec…
Infinite Berry Curvature of Weyl Fermi Arcs
Dennis Wawrzik, Jhih-Shih You, Jorge I. Facio +2
We show that Weyl Fermi arcs are generically accompanied by a divergence of the surface Berry curvature scaling as , where is the distance to a hot-line in the surface B…
Competition of Spinon Fermi Surface and Heavy Fermi Liquids states from the Periodic Anderson to the Hubbard model
Chuan Chen, Inti Sodemann, Patrick A. Lee
We study a model of correlated electrons coupled by tunnelling to a layer of itinerant metallic electrons, which allows to interpolate from a frustrated limit favorable to spin liq…
The Berry Phase Rectification Tensor and The Solar Rectification Vector
O. Matsyshyn, Urmimala Dey, I. Sodemann +1
We introduce an operational definition of the Berry Phase Rectification Tensor as the second-order change of polarization of a material in response to an ideal short pulse of an el…
Excitonic Laughlin States in Ideal Topological Insulator Flat Bands and Possible Presence in Moiré Superlattice Materials
Nikolaos Stefanidis, Inti Sodemann
We investigate few- and many-body states in half-filled maximally symmetric topological insulator flat bands realized by two degenerate Landau levels which experience opposite magn…
