Read-Rezayi fractional Chern insulators in modulated Bernal graphene
Ruth Mora-Soto, André Grossi Fonseca, Raul Perea-Causin +3
Fibonacci anyons provide a universal platform for topological quantum computation, and emerge as low-energy excitations in the Read-Rezayi phase in the fractional qu…
Quantum spin Hall crystals at fractional filling of twisted MoTe
Xiaoyang Shen, Raul Perea-Causin, Christopher Ekman +3
We predict and classify interaction-driven quantum spin Hall crystals (QSHCs), a class of states emerging at fractional filling through an interplay of topology and spontaneous tra…
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…
Quantum anomalous Hall crystals in moiré bands with higher Chern number
Raul Perea-Causin, Hui Liu, Emil J. Bergholtz
The realization of fractional Chern insulators in moiré materials has sparked the search for further novel phases of matter in this platform. In particular, recent works have demon…
Two-spinon effects on the thermal Tonks-Girardeau gas
Felipe Taha Sant'Ana, Hui Liu
We study the effects of the two-spinon excitations on the field-field correlator of the Tonks-Girardeau gas. While these excitations have been previously examined in the ground sta…
Parafermions in Moiré Minibands
Hui Liu, Raul Perea-Causin, Emil J. Bergholtz
Moiré materials provide a remarkably tunable platform for topological and strongly correlated quantum phases of matter. Very recently, the first zero field Abelian fractional Chern…
Non-Abelian Fractional Chern Insulators and Competing States in Flat Moiré Bands
Hui Liu, Zhao Liu, Emil J. Bergholtz
Breakthrough experiments have recently realized fractional Chern insulators (FCIs) in moiré materials. However, all states observed are Abelian, the possible existence of more exot…
Broken Symmetry in Ideal Chern Bands
Hui Liu, Kang Yang, Ahmed Abouelkomsan +2
Recent observations of the fractional anomalous quantum Hall effect in moiré materials have reignited the interest in fractional Chern insulators (FCIs). The chiral limit in which…
Topological fine structure of an energy band
Hui Liu, Cosma Fulga, Emil J. Bergholtz +1
A band with a nonzero Chern number cannot be fully localized by weak disorder. There must remain at least one extended state, which ``carries the Chern number.'' Here we show that…
