The crossover from classical to quantum transport in a weakly-interacting Fermi gas
Hadrien Kurkjian
We present an exact solution of the quantum kinetic equation of a weakly interacting Fermi gas in the crossover from the degenerate Fermi-liquid regime to the classical Boltzmann g…
Exact perturbative expansion of the transport coefficients of a normal low-temperature Fermi gas with contact interactions
Pierre-Louis Taillat, Hadrien Kurkjian
We compute the shear viscosity, thermal conductivity and spin diffusivity of a Fermi gas with short-range interactions in the Fermi liquid regime of the normal phase, that is at te…
Dispersion of first sound in a weakly interacting ultracold Fermi liquid
Thomas Repplinger, Songtao Huang, Yunpeng Ji +2
At low temperature, a normal gas of unpaired spin-1/2 fermions is one of the cleanest realizations of a Fermi liquid. It is described by Landau's theory, where no phenomenological…
Collective excitations of superfluid Fermi gases near the transition temperature
S. N. Klimin, J. Tempere, H. Kurkjian
Studying the collective pairing phenomena in a two-component Fermi gas, we predict the appearance near the transition temperature of a well-resolved collective mode of quadra…
Cumulant theory of the unitary Bose gas: Prethermal and Efimovian dynamics
V. E. Colussi, H. Kurkjian, M. Van Regemortel +4
We study the quench of a degenerate ultracold Bose gas to the unitary regime, where interactions are as strong as allowed by quantum mechanics. We lay the foundations of a cumulant…
Damping of elementary excitations in one-dimensional dipolar Bose gases
Hadrien Kurkjian, Zoran Ristivojevic
In the presence of dipolar interactions the excitation spectrum of a Bose gas can acquire a local minimum. The corresponding quasiparticles are known as rotons. They are gaped and…
