Excitonic condensate in flat valence and conduction bands of opposite chirality
Excitonic Bose-Einstein condensation (EBEC) has drawn increasing attention recently with
the emergence of 2D materials. A general criterion for EBEC, as expected in an excitonic …

Many-body localization from a one-particle perspective in the disordered one-dimensional Bose-Hubbard model
We numerically investigate one-dimensional Bose-Hubbard chains with on-site disorder by
means of exact diagonalization. A primary focus of our work is on characterizing Fock-space …

Disorder-induced Chern insulator in the Harper-Hofstadter-Hatsugai model
Y Kuno - Physical Review B, 2019 - APS
We study the effects of disorder on the topological Chern insulating phase in the Harper-
Hofstadter-Hatsugai (HHH) model. The model with half flux has a bulk band gap and, thus …
