Emergence of a superglass phase in the random hopping Bose-Hubbard model
Anna M. Piekarska, Tadeusz K. Kopeć
We study an experimentally feasible system of strongly correlated bosons with random hoppings, described by the infinite-range Bose-Hubbard model on a lattice with hopping integral…

Spectral properties of excitons in the bilayer graphene
V. Apinyan, T. K. Kopeć
In this paper, we consider the spectral properties of the bilayer graphene with the local excitonic pairing interaction between the electrons and holes. We consider the generalized…

Quantum rotor description of the Mott-insulator transition in the Bose-Hubbard model
T. P. Polak, T. K. Kopeć
We present the novel approach to the Bose-Hubbard model using the quantum rotor description. The effective action formalism allows us to formulate a problem in the…
