Untwisting moiré physics: Almost ideal bands and fractional Chern insulators in periodically strained monolayer graphene
Qiang Gao, Junkai Dong, Patrick Ledwith +2
Moiré systems have emerged in recent years as a rich platform to study strong correlations. Here, we will discuss a simple, experimentally feasible setup based on periodically stra…
Exact Many-Body Ground States from Decomposition of Ideal Higher Chern Bands: Applications to Chirally Twisted Graphene Multilayers
Junkai Dong, Patrick J. Ledwith, Eslam Khalaf +2
Motivated by the higher Chern bands of twisted graphene multilayers, we consider flat bands with arbitrary Chern number with ideal quantum geometry. While bands differ fr…
Vortexability: A Unifying Criterion for Ideal Fractional Chern Insulators
Patrick J. Ledwith, Ashvin Vishwanath, Daniel E. Parker
Fractional Chern insulators realize the remarkable physics of the fractional quantum Hall effect (FQHE) in crystalline systems with Chern bands. The lowest Landau level (LLL) is kn…
Dirac cone spectroscopy of strongly correlated phases in twisted trilayer graphene
Cheng Shen, Patrick J. Ledwith, Kenji Watanabe +4
Mirror-symmetric magic-angle twisted trilayer graphene (MATTG) hosts flat electronic bands close to zero energy, and has been recently shown to exhibit abundant correlated quantum…
