Nonadiabatic superconductivity in Li-intercalated hexagonal boron nitride bilayer
K. A. Szewczyk, I. A. Domagalska, A. P. Durajski +1
In the case of Li-intercalated hexagonal boron nitride bilayer (Li-hBN), the vertex corrections of electron-phonon interaction cannot be omitted. This is evidenced by the very high…
The unbalanced phonon-induced superconducting state on a square lattice beyond the static boundary
K. A. Szewczyk, M. W. Jarosik, A. P. Durajski +1
The paper presents our verification of induction of the superconducting state on a square lattice by the linear electron-phonon interaction for values of the unbalance parameter ($…
Interaction of the hydrogen molecule with the environment: stability of the system
I. A. Wrona, M. W. Jarosik, R. Szczȩśniak +3
We study the stability of the hydrogen molecule interacting with the environment according to the balanced gain and loss energy scheme. We determined the properties of the molecule…
The thermodynamic critical field and specific heat of superconducting state in phosphorene under strain
Kamila A. Szewczyk, Adam Z. Kaczmarek, Ewa A. Drzazga
In this work we present the thermodynamic properties of the superconducting state in phosphorene. In particular, we have examined the electron doped ($n_{D}=1.3\times 10^{14} \rm{c…
Influence of strong-coupling and retardation effects on superconducting state in compound
A. M. Bujak, K. A. Szewczyk, M. Kostrzewa +2
In the framework of strong-coupling formalism, we have calculated the thermodynamic parameters of superconducting state in the compound. The values of critical tempe…
Unbalanced superconductivity induced by the constant electron-phonon coupling on a square lattice
Kamila A. Szewczyk, Radosław Szczȩśniak, Dominik Szczȩśniak
In the present paper, we analyze the properties of the unbalanced superconducting state on a square lattice with the constant value of the electron-phonon coupling function. We con…
