Anderson-Bogoliubov collective excitations in superfluid Fermi gases at nonzero temperatures
S. N. Klimin, H. Kurkjian, J. Tempere
The Anderson-Bogoliubov branch of collective excitations in a condensed Fermi gas is treated using the effective bosonic action of Gaussian pair fluctuations. The spectra of collec…
Leggett collective excitations in a two-band Fermi superfluid at finite temperatures
S. N. Klimin, H. Kurkjian, J. Tempere
The Leggett collective excitations for a two-band Fermi gas with s-wave pairing and Josephson interband coupling in the BCS-BEC crossover at finite temperatures are investigated wi…
Superconductivity in SrTiO: dielectric function method for non-parabolic bands
S. N. Klimin, J. Tempere, J. T. Devreese +3
The dielectric function method for superconductivity has been applied to SrTiO accounting for the non-parabolic dispersion of charge carriers in the conduction band and for t…
Phononic collective excitations in superfluid Fermi gases at nonzero temperatures
S. N. Klimin, J. Tempere, H. Kurkjian
We study the phononic collective modes of the pairing field and their corresponding signature in both the order-parameter and density response functions for a superfluid Fermi…
Multiband superconductivity due to the electron - LO-phonon interaction in strontium titanate and on a SrTiO3/LaAlO3 interface
S. N. Klimin, J. Tempere, J. T. Devreese +1
In strontium titanate, the Froehlich electron - LO-phonon interaction dominates the electron response and can also provide superconductivity. Because of high LO-phonon frequencies…
All-coupling polaron optical response: analytic approaches beyond the adiabatic approximation
S. N. Klimin, J. Tempere, J. T. Devreese
In the present work, the problem of an all-coupling analytic description for the optical conductivity of the Froehlich polaron is treated, with the goal being to bridge the gap in…
