Field-tuned and zero-field fractional Chern insulators in magic angle graphene
Daniel Parker, Patrick Ledwith, Eslam Khalaf +7
In contrast to the fractional quantum Hall (FQH) effect, where electron density fixes the applied magnetic field, fractional Chern insulators (FCIs) can realize FQH states in compa…
From electrons to baby skyrmions in Chern ferromagnets: A topological mechanism for spin-polaron formation in twisted bilayer graphene
Eslam Khalaf, Ashvin Vishwanath
The advent of Moiré materials has galvanized interest in the nature of charge carriers in topological bands. In contrast to conventional materials where charge carriers are electro…
Anderson localization at the boundary of a two-dimensional topological superconductor
Daniil S. Antonenko, Eslam Khalaf, Pavel M. Ostrovsky +1
A one-dimensional boundary of a two-dimensional topological superconductor can host a number of topologically protected chiral modes. Combining two topological superconductors with…
TB or not TB? Contrasting properties of twisted bilayer graphene and the alternating twist -layer structures ()
Patrick J. Ledwith, Eslam Khalaf, Ziyan Zhu +3
The emergence of alternating twist multilayer graphene (ATMG) as a generalization of twisted bilayer graphene (TBG) raises the question - in what important ways do these systems di…
Family of ideal Chern flat bands with arbitrary Chern number in chiral twisted graphene multilayers
Patrick J. Ledwith, Ashvin Vishwanath, Eslam Khalaf
We consider a family of twisted graphene multilayers consisting of -untwisted chirally stacked layers, e.g., AB, ABC, etc, with a single twist on top of -untwisted {chirally…
Fractional Chern insulators in magic-angle twisted bilayer graphene
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +12
Fractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall states that may provide a new avenue toward manipulating non-abelian excitations. Early theoreti…
