We theoretically analyze inverse radio-frequency (rf) spectroscopy experiments in two-component Fermi gases. We consider a small number of impurity atoms interacting strongly with a bath of majority… Expand

We report the experimental measurement of the equation of state of a two-dimensional Fermi gas with attractive s-wave interactions throughout the crossover from a weakly coupled Fermi gas to a Bose… Expand

The thermodynamic and transport properties of the unitary Fermi gas at finite temperature T are governed by a quantum critical point at T = 0 and zero density. We compute the universal shear… Expand

A light impurity in a Fermi sea undergoes a transition from a polaron to a molecule for increasing interaction. We develop a method to compute the spectral functions of the polaron and molecule in a… Expand

It is shown that measuring the difference in occupation between even and odd sites, starting from a prepared density-wave state, provides clear signatures of localization, and confirms as hallmarks of the many-body localized phase a logarithmic increase of the entanglement entropy in time and Poissonian level statistics.Expand

The thermodynamic properties and the spectral function for a homogeneous two-dimensional Fermi gas in the normal state are determined using the Luttinger-Ward, or self-consistent T-matrix, approach and it is suggested that temperature has a pronounced effect on the pressure in the crossover from weak to strong coupling.Expand

It is shown that the spin transport in the unitary Fermi gas using the strong-coupling Luttinger-Ward theory achieves a minimum value of D(s) and a maximum value of Γ(sd) in the quantum degenerate regime.Expand

For the quantum degenerate regime I report numerical Luttinger-Ward results for the contact correlator and the dynamical bulk viscosity throughout the BEC-BCS crossover, and the ratio of bulk to shear viscosities ζ/η is found to exceed the kinetic theory prediction in the quantum progressive regime.Expand

h/m in the quantum degenerate regime and are strongly suppressed by medium scattering, and we discuss the importance of the spin-rotation effect. In two dimensions, D⊥ attains a minimum at strong… Expand
