Physics of ultracold Fermi gases revealed by spectroscopies
نویسنده
چکیده
This article provides a brief review of how various spectroscopies have been used to investitage many-body quantum phenomena in the context of ultracold Fermi gases. In particular, work done with RF spectroscopy, Bragg spectroscopy and lattice modulation spectroscopy is considered. The theoretical basis of these spectroscopies, namely linear response theory in the many-body quantum physics context is briefly presented. Experiments related to the BCS–BEC crossover, imbalanced Fermi gases, polarons, possible pseudogap and Fermi liquid behaviour and measuring the contact are discussed. Remaining open problems and goals in the field are sketched from the perspective how spectroscopies could contribute.

Ultracold Fermi gases in the BEC-BCS crossover: a review from the Innsbruck perspective
By the time of the “Enrico Fermi” Summer School in June 2006, quantum degeneracy in ultracold Fermi gases has been reported by 13 groups worldwide [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]. The field is rapidly expanding similar to the situation of Bose-Einstein condensation at the time of the “Enrico Fermi” Summer School in 1998 [14]. The main two species for the creation of ultracold Fermi ...
متن کاملMolecular regimes in ultracold Fermi gases
The use of Feshbach resonances for tuning the interparticle interaction in ultracold Fermi gases has led to remarkable developments, in particular to the creation and Bose-Einstein condensation of weakly bound diatomic molecules of fermionic atoms. These are the largest diatomic molecules obtained so far, with a size of the order of thousands of angstroms. They represent novel composite bosons,...
متن کاملPseudogap phenomena in ultracold atomic Fermi gases
The pairing and superfluid phenomena in a two-component ultracold atomic Fermi gas is an analogue of Cooper pairing and superconductivity in an electron system, in particular, the high Tc superconductors. Owing to the various tunable parameters that have been made accessible experimentally in recent years, atomic Fermi gases can be explored as a prototype or quantum simulator of superconductors...
متن کاملRadio-Frequency Spectroscopy of Ultracold Atomic Fermi Gases
This thesis presents experiments investigating the phase diagram of ultracold atomic Fermi gases using radio-frequency spectroscopy. The tunability of many experimental parameters including the temperature, the interparticle interaction strength and the relative population of different fermions allows to access very different physical regimes. Radio-frequency spectroscopy has been developed int...
متن کاملUltracold Molecules from Ultracold Atoms: Interactions in Sodium and Lithium Gas
The thesis presents results from experiments in which ultracold Sodium-6 and Lithium-23 atomic gases were studied near a Feshbach resonance at high magnetic fields. The enhanced interactions between atoms in the presence of a molecular state enhance collisions, leading to inelastic decay and loss, many-body dynamics, novel quantum phases, and molecule formation. Experimental data is presented a...
