Thermodynamic and electromagnetic properties of the eta-pairing superconductivity in the Penson-Kolb model
Wojciech R. Czart, Konrad J. Kapcia, Roman Micnas +1
In the paper, we study the thermodynamic and electromagnetic properties of the Penson-Kolb (PK) model, i.e., the tight-binding model for fermionic particles with the pair-hopping i…
On the Boson-Fermion resonant model on a lattice
R. Micnas
We review briefly the properties of a mixture of mutually interacting bosons (bound electron pairs) and itinerant fermions on a lattice (the boson-fermion model). The calculations…
Effect of boson on-site repulsion on the superfluidity in the boson-fermion-Hubbard model
A. S. Sajna, R. Micnas
We analyze the finite-temperature phase diagram of the boson-fermion-Hubbard model with Feshbach converting interaction, using the coherent-state path-integral method. We show that…
Conductivity of strongly correlated bosons in optical lattices in an Abelian synthetic magnetic field
A. S. Sajna, T. P. Polak, R. Micnas
Topological phase engineering of neutral bosons loaded in an optical lattice opens a new window for manipulating of transport phenomena in such systems. Exploiting the Bose Hubbard…
Stability of superfluid phases in the 2D Spin-Polarized Attractive Hubbard Model
Agnieszka Kujawa-Cichy, Roman Micnas
We study the evolution from the weak coupling (BCS-like limit) to the strong coupling limit of tightly bound local pairs (LP's) with increasing attraction, in the presence of the Z…
Real space inhomogeneities in high temperature superconductors: the perspective of two-component model
J. Krzyszczak, T. Domanski, K. I. Wysokinski +2
The two-component model of high temperature superconductors in its real space version has been solved using Bogoliubov-de Gennes equations. The disorder in the electron and boson s…
