Momentum resolved radio frequency spectroscopy in trapped fermi gases.

چکیده
We address recent momentum-resolved radio frequency (rf) spectroscopy experiments, showing how they yield more stringent tests than other comparisons with theory, associated with the ultracold Fermi gases. We demonstrate that, by providing a clear dispersion signature of pairing, they remove the ambiguity plaguing the interpretation of previous rf experiments. Our calculated spectral intensities are in semiquantitative agreement with the data. Even in the presence of a trap, the spectra are predicted to exhibit two BCS-like branches.

Spin-orbit coupled degenerate Fermi gases.
In this Letter, we report the first experimental realization and investigation of a spin-orbit coupled Fermi gas. Both spin dephasing in spin dynamics and momentum distribution asymmetry of the equilibrium state are observed as hallmarks of spin-orbit coupling in a Fermi gas. The single particle dispersion is mapped out by using momentum-resolved radio-frequency spectroscopy. From momentum dist...
متن کاملTheory of radio frequency spectroscopy experiments in ultracold Fermi gases and their relation to photoemission in the cuprates
In this paper we present an overview of radio frequency (RF) spectroscopy in the atomic Fermi superfluids with the ultimate goal of suggesting new directions in the cold gas research agenda from the condensed matter perspective. We review the experimental and theoretical literature on cold gases and the photoemission spectroscopy of the cuprates particularly as it pertains to areas of overlap. ...
متن کاملMomentum-resolved spectroscopy of a Fermi liquid
We consider a recent momentum-resolved radio-frequency spectroscopy experiment, in which Fermi liquid properties of a strongly interacting atomic Fermi gas were studied. Here we show that by extending the Brueckner-Goldstone model, we can formulate a theory that goes beyond basic mean-field theories and that can be used for studying spectroscopies of dilute atomic gases in the strongly interact...
متن کاملTomographic rf spectroscopy of a trapped Fermi gas at unitarity.
We present spatially resolved radio-frequency spectroscopy of a trapped Fermi gas with resonant interactions and observe a spectral gap at low temperatures. The spatial distribution of the spectral response of the trapped gas is obtained using in situ phase-contrast imaging and 3D image reconstruction. At the lowest temperature, the homogeneous rf spectrum shows an asymmetric excitation line sh...
متن کاملRadio-frequency spectroscopy and the pairing gap in trapped Fermi gases
We present a theoretical interpretation of radio frequency RF pairing gap experiments in trapped atomic Fermi gases, over the entire range of the BCS–Bose-Einstein condensation BEC crossover, for temperatures above and below Tc. Our calculated RF excitation spectra, as well as the density profiles on which they are based, are in semiquantitative agreement with experiment. We provide a detailed ...
