Nature of the bosonic edge phase in a double quantum spin Hall insulator
Andreas Feuerpfeil, Ronny Thomale, Trithep Devakul +2
Field-theoretic analysis has predicted that the edge of a double quantum spin Hall insulator (DQSHI) can undergo an interaction-driven transition from a phase with fermionic edge m…
Valley-Helical Superconductivity Driven by Repulsion and Quantum Geometry: Applications to Time-Reversal Symmetric Rhombohedral Graphene
Julian May-Mann, Trithep Devakul, Gal Shavit
Motivated by the recent experimental signatures of chiral superconductivity in valley-polarized graphene- and transition-metal-dichalcogenide-based systems, we investigate the poss…
Quantized Transport through a Supermoiré Chern Mosaic
Li-Qiao Xia, Aviram Uri, Zachary W. Gomez +8
Magic-angle helical trilayer graphene---three graphene layers sequentially twisted in the same direction by ---relaxes into a mosaic of domains that, at zero field,…
Skyrmion Fractional Chern Insulator: An Intrinsically Multiband Route to Fractionalization in Rhombohedral Graphene
Julian May-Mann, Tixuan Tan, Patrick J. Ledwith +2
We propose an unconventional microscopic origin for the fractional quantum anomalous Hall (FQAH) effect in rhombohedral graphene moiré superlattices: skyrmion fractionalization. We…
Anyon Crystals and Hall Crystals in a Periodic Potential
Sayak Bhattacharjee, Julian May-Mann, Srinivas Raghu
We obtain integer and fractional quantum Hall crystals as ground states of a two-dimensional electron system subject to a strong perpendicular magnetic field and a periodic potenti…
Fermiology and the Candidate Chiral Superconductor in Rhombohedral Tetralayer Graphene
Sandesh S. Kalantre, Ben H. Alexander, Julian May-Mann +11
Chiral superconductivity, in which the phase of the superconducting order parameter winds in momentum space, has long been sought for its close link to topological superconductivit…
Mesoscopic transport in a Chern mosaic
Sayak Bhattacharjee, Julian May-Mann, Yves H. Kwan +2
We analyze mesoscopic electronic transport in a Chern mosaic: a regular pattern of domains whose electronic bands carry differing local Chern numbers. An example platform where a C…
Composite boson theory of Hall crystals and their transitions to Wigner crystals
Julian May-Mann, Sayak Bhattacharjee, Srinivas Raghu
We consider the crystallization of a two-dimensional electron system in a perpendicular magnetic field using composite boson theory. There are three possible states to consider: th…
