First-principles theory of phonon renormalization from nonlinear electron-phonon interactions
Florian Kluibenschedl, Matthew Houtput, Jacques Tempere +3
Electron-phonon interactions renormalize phonon frequencies and lifetimes and are central to the dynamical properties of solids. While these effects are usually described within li…
Signature in sound-mode of the exciton bilayer two-dimensional superfluid transition
Giovanni Midei, Filippo Pascucci, Milorad V. Milosevìc +3
Obtaining definitive evidence of exciton superfluidity in electron-hole bilayers in zero magnetic field remains a major longstanding challenge since the condensate is electrically…
Importance of nonlinear long-range electron-phonon interaction for the carrier mobility of anharmonic halide perovskites
Matthew Houtput, Ingvar Zappacosta, William Wenborn +4
The interaction between the electrons and the lattice vibrations in a solid is responsible for various important effects, such as formation of polarons, temperature dependent bandg…
Effective Three-Boson Interactions using a Separable Potential
Corinne Beckers, Jacques Tempere, Jeff Maki +1
Effective field theories (EFTs) are widely used to study many-body systems by describing two-body interactions using zero-ranged contact potentials. However, when extended to three…
Effect of Population Imbalance on Vortex Mass in Superfluid Fermi Gases
Lucas Levrouw, Hiromitsu Takeuchi, Jacques Tempere
One of the fundamental parameters associated with quantized vortices in superfluids is the vortex mass, which is the inertia of a vortex. As of yet, this mass has not been observed…
A Gross-Pitaevskii theory for an excitonic incompressible Bose solid
Sara Conti, Andrey Chaves, Alexander R. Hamilton +3
We show that interlayer excitons in double-layer semiconductor heterostructures can form a Bose solid, which is an incompressible supersolid characterized by exactly one boson per…
Vortex Mass in Superfluid Fermi Gases along the BEC-BCS Crossover
Lucas Levrouw, Hiromitsu Takeuchi, Jacques Tempere
Vortex mass is a key concept in the study of superfluid dynamics, referring to the inertia of vortices in a superfluid, which affects their motion and behavior. Despite being an im…
Linear response of a superfluid Fermi gas inside its pair-breaking continuum
H. Kurkjian, J. Tempere, S. N. Klimin
We study the signatures of the collective modes of a superfluid Fermi gas in its linear response functions for the order-parameter and density fluctuations in the Random Phase Appr…
Diversified vortex phase diagram for a rotating trapped two-band Fermi gas in the BCS-BEC crossover
S. N. Klimin, J. Tempere, M. V. Milošević
We report the equilibrium vortex phase diagram of a rotating two-band Fermi gas confined to a cylindrically symmetric parabolic trapping potential, using the recently developed fin…
Finite temperature vortices in a rotating Fermi gas
S. N. Klimin, J. Tempere, N. Verhelst +1
Vortices and vortex arrays have been used as a hallmark of superfluidity in rotated, ultracold Fermi gases. These superfluids can be described in terms of an effective field theory…
