Physical manifestation of replica symmetry breaking in a quantum glass of bosons with off-diagonal disorder
Anna M. Piekarska, Tadeusz K. Kopeć
Glassiness occurs when disorder and frustration cause local degrees of freedom to freeze despite the lack of long-range order. In systems of interacting bosons, such glassiness may…

Reentrant phase transitions involving glassy and superfluid orders in the random hopping Bose-Hubbard model
Anna M. Piekarska, Tadeusz K. Kopeć
We study a system of strongly correlated bosons with off-diagonal disorder, i.e., randomness in the kinetic energy, and find a family of reentrant phase transitions that occur as a…

Excitonic effects in twisted bilayer graphene
V. Apinyan, T. K. Kopeć
In the present work, we consider the excitonic effects in the twisted bilayer graphene (tBLG) within the rotated bilayer Hubbard model. Both, intralayer and interlayer Coulomb inte…
