Spectral properties and observables in ultracold Fermi gases

POSTER

Abstract

We calculate non-perturbative self-consistent fermionic and bosonic spectral functions of ultracold Fermi gases directly in real-time. The spectral functions are then used for the determination of the equation of state, the Tan contact and ejection rf spectra at unitarity. These results are compared to experimental data, the self-consistent T-matrix approach and lattice results. Our approach offers a wide range of applications, including the ab initio calculation of transport and spectral properties of the superfluid phase in the BCS-BEC crossover.
