Non-Hermitian Exceptional Topology on a Klein Bottle Photonic Circuit
Ze-Sheng Xu, J. Lukas K. König, Andrea Cataldo +8
Non-Hermitian physics has unlocked a wealth of unconventional wave phenomena beyond the reach of Hermitian systems, with exceptional points (EPs) driving enhanced sensitivity, nonr…
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 fraction…
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…
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 demon…
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 exo…
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 demo…
