Fröhlich Polarons. Lecture course including detailed theoretical derivations -- 10th edition
J. T. Devreese
In the present course, an overview is presented of the fundamentals of continuum-polaron physics, which provide the basis of the analysis of polaron effects in ionic crystals and p…
Reply to "On the cutoff parameter in the translation-invariant theory of the strong coupling polaron"
S. N. Klimin, J. T. Devreese
The present work is a reply to the paper [1]. It is proven that the argumentation of Ref. [1] is inconsistent. The variational functional for the polaron ground state energy consid…
Comments on "Translation-invariant bipolarons and the problem of high-temperature superconductivity"
S. N. Klimin, J. T. Devreese
We comment on the recent results of Refs. [1, 2] on the bipolaron problem derived using an approximation of Gross - Tulub. It is proved that, contrary to the claim made in Refs. [1…

Feynman's path-integral polaron treatment approached using time-ordered operator calculus
S. N. Klimin, J. T. Devreese
The Feynman all-coupling variational approach for the polaron is re-formulated and extended using the Hamiltonian formalism with time-ordered operator calculus. Special attention i…
Phase separation in imbalanced fermion superfluids beyond mean-field
J. Tempere, S. N. Klimin, J. T. Devreese
The density distributions of the two components of a trapped, ultracold Fermi gas with population imbalance reveal the effect of imbalance on superfluid pairing. We develop a path-…
Critical currents in the BEC/BCS crossover regime
J. Tempere, J. T. Devreese
Both the trapping geometry and the interatomic interaction strength of a dilute ultracold fermionic gas can be well controlled experimentally. When the interactions are tuned to st…
The vortex state in the BEC to BCS crossover: a path-integral description
J. Tempere, M. Wouters, J. T. Devreese
We derive a path-integral description of the vortex state of a fermionic superfluid in the crossover region between the molecular condensate (BEC) regime and the Cooper pairing (BC…
Sonoluminescence and collapse dynamics of multielectron bubbles in helium
J. Tempere, I. F. Silvera, S. Rekhi +1
Multielectron bubbles (MEBs) differ from gas-filled bubbles in that it is the Coulomb repulsion of a nanometer thin layer of electrons that forces the bubble open rather than the p…
