Optical response of an interacting polaron gas in strongly polar crystals
S. N. Klimin, J. Tempere, J. T. Devreese +2
Optical conductivity of an interacting polaron gas is calculated within an extended random phase approximation which takes into account mixing of collective excitations of the elec…
Plasmonic Cooper pairing in single layer graphene
Dietrich Elst, Sergei N. Klimin, Jacques Tempere
The dielectric function method (DFM), which uses a non-adiabatic approach to calculate the critical temperatures for superconductivity, has been quite successful in describing supe…
Beyond mean-field corrections to the quasiparticle spectrum of superfluid Fermi gases
Senne Van Loon, Jacques Tempere, Hadrien Kurkjian
We investigate the fermionic quasiparticle branch of superfluid Fermi gases in the BCS-BEC crossover and calculate the quasiparticle lifetime and energy shift due to its coupling w…
Feynman path-integral treatment of the Bose polaron beyond the Fröhlich model
Timour Ichmoukhamedov, Jacques Tempere
An impurity immersed in a Bose-Einstein condensate is no longer accurately described by the Fröhlich Hamiltonian as the coupling between the impurity and the boson bath gets strong…
Finite element simulation of the liquid-liquid transition to metallic hydrogen
Matthew Houtput, Jacques Tempere, Isaac F. Silvera
Hydrogen at high temperature and pressure undergoes a phase transition from a liquid molecular phase to a conductive atomic state, or liquid metallic hydrogen, sometimes referred t…
Crossover between snake instability and Josephson instability of dark solitons in superfluid Fermi gases
Wout Van Alphen, Hiromitsu Takeuchi, Jacques Tempere
Dark solitons in superfluid Bose gases decay through the snake instability mechanism, unless they are strongly confined. Recent experiments in superfluid Fermi gases have also inte…
