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 observation…
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, twisted…
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…
Topological quantum phase transitions driven by a displacement field in the twisted MoTe2 bilayers
Prakash Sharma, Yang Peng, D. N. Sheng
We study twisted bilayer MoTe systems at fractional fillings of the lowest hole band under an applied out-of-plane displacement field. By employing exact diagonalization in fin…
Real-space topological invariant for time-quasiperiodic Majoranas
Zihao Qi, Ilyoun Na, Gil Refael +1
When subjected to quasiperiodic driving protocols, superconducting systems have been found to harbor robust time-quasiperiodic Majorana modes, extending the concept beyond static a…
