By using a non-self-consistent many-body T -matrix theory, we calculate the finite-temperature Raman spectroscopy of a mobile impurity immersed in a Fermi bath in three dimensions. The dependences of the Raman spectrum on the transferred momentum, temperature, and impurity-bath interaction are discussed in detail. We confirm that the peak in the Raman spectrum shows a weaker dependence on the impurity concentration than that in the radio-frequency spectroscopy, due to the nonzero transferred…

Fermi polarons at finite temperature: Spectral function and rf spectroscopy

We present a systematic study of a mobile impurity immersed in a three-dimensional Fermi sea of fermions at finite temperature, by using the standard non-self-consistent many-body T -matrix theory

Thermodynamic signatures of the polaron-molecule transition in a Fermi gas

We consider the highly spin-imbalanced limit of a two-component Fermi gas, where there is a small density of $\downarrow$ impurities attractively interacting with a sea of $\uparrow$ fermions. In the

Boiling a Unitary Fermi Liquid.

In the transition region between the quantum degenerate and classical regime, the spectral width attains its maximum, on the scale of the Fermi energy, indicating the breakdown of a quasiparticle description.

Exact Quasiparticle Properties of a Heavy Polaron in BCS Fermi Superfluids.

We present the Ramsey response and radio-frequency spectroscopy of a heavy impurity immersed in an interacting Fermi superfluid, using the exact functional determinant approach. We describe the Fermi

Polaron-to-molecule transition in a strongly imbalanced Fermi gas

A single down spin Fermion with an attractive, zero range interaction with a Fermi sea of up-spin Fermions forms a polaronic quasiparticle. The associated quasipart icle weight vanishes beyond a

Attractive and repulsive Fermi polarons in two dimensions

Fermi polarons are created and investigated in a two-dimensional, spin-imbalanced Fermi gas, measuring their spectral function using momentum-resolved photoemission spectroscopy and finding evidence for a disputed pairing transition between polarons and tightly bound dimers, which provides insight into the elementary pairing mechanism of imbalanced, strongly coupled two- dimensional Fermu gases.

Universal many-body response of heavy impurities coupled to a Fermi sea: a review of recent progress

It is shown that the physics of the orthogonality catastrophe is experimentally observable up to temperatures and it is proved that within the considered model the fastest rate of long-time decoherence is given by the Toeplitz determinants.

Analytical theory of the dressed bound state in highly polarized Fermi gases

We present an analytical treatment of a single ↓-atom within a Fermi sea of ↑-atoms, when the interaction is strong enough to produce a bound state, dressed by the Fermi sea. Our method makes use of

Heavy polarons in ultracold atomic Fermi superfluids at the BEC-BCS crossover: Formalism and applications

We investigate the system of a heavy impurity embedded in a paired two-component Fermi gas at the crossover from a Bose-Einstein condensate (BEC) to a Bardeen–Cooper–Schrieffer (BCS) superfluid via

Normal state of highly polarized fermi gases: simple many-body approaches.

Surprisingly, the results suggest that, even at unitarity, the effect of interactions is fairly weak and can be accurately described using single particle-hole excitations.
