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…
Symmetry Origin of Lattice Vibration Modes in Twisted Multilayer Graphene: Phasons vs Moiré Phonons
Qiang Gao, Eslam Khalaf
Lattice dynamics play a crucial role in the physics of Moiré systems. In twisted bilayer graphene (TBG), it was shown that, in addition to the graphene phonons, there is another se…
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…
Emergence of Correlations in Alternating Twist Quadrilayer Graphene
G. William Burg, Eslam Khalaf, Yimeng Wang +3
Recently, alternating twist multilayer graphene (ATMG) has emerged as a family of moiré systems that share several fundamental properties with twisted bilayer graphene, and are exp…
