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…
Finite temperature effective field theory for dark solitons in superfluid Fermi gases
S. N. Klimin, J. Tempere, J. T. Devreese
We use a finite temperature effective field theory recently developed for superfluid Fermi gases to investigate the properties of dark solitons in these superfluids. Our approach p…
Strong coupling treatment of the polaronic system consisting of an impurity in a condensate
W. Casteels, T. Van Cauteren, J. Tempere +1
The strong coupling treatment of the Fröhlich-type polaronic system, based on a canonical transformation and a standard Landau-Pekar type variational wave function, is applied to t…
On the ground state energy of a gas of interacting polarons in a magnetic field
K. Putteneers, F. Brosens, S. N. Klimin +1
The ground-state energy of a three-dimensional polaron gas in a magnetic field is investigated. An upper bound for the ground-state energy is derived within a variational approach…
Dynamical Exchange Effects in a Two-Dimensional Many-Polaron Gas
K. J. Hameeuw, J. Tempere, F. Brosens +1
We calculate the influence of dynamical exchange effects on the response properties and the static properties of a two-dimensional many-polaron gas. These effects are not manifeste…
Magnetic susceptibility of ultra-small superconductor grains
V. N. Gladilin, V. M. Fomin, J. T. Devreese
For assemblies of superconductor nanograins, the magnetic response is analyzed as a function of both temperature and magnetic field. In order to describe the interaction energy of…
