Kekulé spiral order in magic-angle graphene: a density matrix renormalization group study
Tianle Wang, Daniel E. Parker, Tomohiro Soejima +4
When the two layers of a twisted moiré system are subject to different degrees of strain, the effect is amplified by the inverse twist angle, e.g., by a factor of 50 in magic angle…
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…
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…
Optically-induced Umklapp shift currents in striped cuprates
Pavel E. Dolgirev, Marios H. Michael, Jonathan B. Curtis +6
Motivated by recent experiments that observed low-frequency second-order optical responses in doped striped superconductors, here we investigate the nonlinear electrodynamics of sy…
