Topological Order and Non-Hermitian Skin Effect in Generalized Ideal Chern Bands
Jiong-Hao Wang, Christopher Ekman, Raul Perea-Causin +2
Fractionalization in ideal Chern bands and non-Hermitian topological physics are two active but so far separate research directions. Merging these, we generalize the notion of idea…
Probing Topological Stability with Nonlocal Quantum Geometric Markers
Quentin Marsal, Hui Liu, Emil J. Bergholtz +1
Spatially resolved local quantum geometric markers play a crucial role in the diagnosis of topological phases without long-range translational symmetry, including amorphous systems…
Breakdown of Non-Bloch Bulk-Boundary Correspondence and Emergent Topology in Floquet Non-Hermitian Systems
Hong Wu, Xue-Min Yang, Hui Liu
Topological edge states in gaps of non-Hermitian systems are robust due to topological protection. Using the non-Hermitian Floquet Su-Schrieffer-Heeger model, we show that this rob…
Topological Order Without Band Topology in Moiré Graphene
Hui Liu, Raul Perea-Causin, Zhao Liu +1
The discovery of zero-field fractional Chern insulators (FCIs) in moiré materials has attracted intense interest in the interplay between topology and correlations. Here, we demons…
Exciton fractional Chern insulators in moiré heterostructures
Raul Perea-Causin, Hui Liu, Emil J. Bergholtz
Moiré materials have emerged as a powerful platform for exploring exotic quantum phases. While recent experiments have unveiled fractional Chern insulators exhibiting the fractiona…
