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…
ARPES signatures of trions in van der Waals materials
Giuseppe Meneghini, Maja Löwe, Raul Perea-Causin +5
Angle-resolved photoemission spectroscopy (ARPES) has recently emerged as a direct probe of excitonic correlations in two-dimensional semiconductors, resolving their dispersion and…
Electrically tunable ultrafast dynamics and interactions of hybrid excitons in a 2D semiconductor bilayer
Edoardo Lopriore, Charalambos Louca, Armando Genco +12
Extended efforts have been devoted to the study of strongly-interacting excitons and their dynamics, towards macroscopic quantum states of matter such as Bose-Einstein condensates…
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…
