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…
High spin, low spin or gapped spins: magnetism in the bilayer nickelates
Hanbit Oh, Yi-Ming Wu, Julian May-Mann +4
Inspired by the recent discovery of high-temperature superconductivity in bilayer nickelates, we investigate the role of magnetism emerging from a hypothetical insulating par…
Imaging supermoiré relaxation in helical trilayer graphene
Jesse C. Hoke, Yifan Li, Yuwen Hu +5
In twisted van der Waals materials, local atomic relaxation can alter the underlying electronic structure. Characterizing lattice reconstruction and its susceptibility to strain is…
