High energy shift in the optical conductivity spectrum of the bilayer graphene

V. Apinyan, T. K. Kopeć

We calculate theoretically the optical conductivity in the bilayer graphene by considering Kubo-Green-Matsubara formalism. Different regimes of the interlayer coupling parameter ha…

Two-orbital Hubbard model vs spin $S = 1$ Heisenberg model: studies on clusters

R. Lemański, J. Matysiak

We perform exact numeric calculations for the two-orbital Hubbard model on the four-site cluster. In the limit of large on-site coupling the model becomes equivalent to the spin $S…

Superconductivity in the Superhard Boride WB $_{4.2}$

Elizabeth M. Carnicom, Judyta Strychalska-Nowak, Piotr Wiśniewski +4

We show that the superhard boride WB $_{4.2}$ is a superconductor with a T $_{c}$ of 2.05(5) K. Temperature-dependent magnetic susceptibility, electrical resistivity, and specific heat…
