Engineering micromotion in Floquet prethermalization via space-time symmetries
Ilyoun Na, Jack Kemp, Sinéad M. Griffin +1
We present a systematic framework for Floquet prethermalization under strong resonant driving, emphasizing the pivotal role of dynamical space-time symmetries. Our approach demonst…

Quantum anomalous Hall effects and emergent Hall ferromagnets at fractional filling of helical trilayer graphene
Sen Niu, Jason Alicea, D. N. Sheng +1
Helical trilayer graphene realizes a versatile moiré system for exploring correlated topological states emerging from high Chern bands. Motivated by recent experimental observatio…

Quantum phase diagram and non-abelian Moore-Read state in double twisted bilayer graphene
Sen Niu, Yang Peng, D. N. Sheng
Experimental realizations of Abelian fractional Chern insulators (FCIs) have demonstrated the potentials of moiré systems in synthesizing exotic quantum phases. Remarkably, twiste…
