  author={Markus Greiner and Cindy A. Regal and Deborah S. Jin},
The realization of superfluidity in a dilute gas of fermionic atoms, analogous to superconductivity in metals, represents a long-standing goal of ultracold gas research. In such a fermionic superfluid, it should be possible to adjust the interaction strength and tune the system continuously between two limits: a Bardeen–Cooper–Schrieffer (BCS)-type superfluid (involving correlated atom pairs in momentum space) and a Bose–Einstein condensate (BEC), in which spatially local pairs of atoms are… 
Vortices and superfluidity in a strongly interacting Fermi gas
Observation of vortex lattices in a strongly interacting, rotating Fermi gas that provide definitive evidence for superfluidity are reported and the crossover from a Bose–Einstein condensate of molecules to a Bardeen–Cooper–Schrieffer superfluid of loosely bound pairs is explored.
High-temperature superfluidity in an ultracold Fermi gas
This thesis presents experiments in which a strongly interacting gas of fermions was brought into the superfluid regime. The strong interactions are induced by a Feshbach scattering resonance that
Thermodynamics of Fermi Gases
Recently, ultra-cold atoms have established a very fruitful connection with condensed matter physics, nuclear physics, astrophysics, and high energy physics on many-body problems in strongly
Evidence for superfluidity of ultracold fermions in an optical lattice
The observation of distinct interference peaks when a condensate of fermionic atom pairs is released from an optical lattice, implying long-range order (a property of a superfluid), means that s-wave pairing and coherence of fermanion pairs have now been established in a lattice potential, in which the transport of atoms occurs by quantum mechanical tunnelling and not by simple propagation.
Theory of ultracold atomic Fermi gases
The physics of quantum degenerate atomic Fermi gases in uniform as well as in harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is given to the effect of
Generalized BEC and crossover theories of superconductors and ultracold Fermi gases
Abstract The generalized Bose–Einstein condensation (GBEC) formalism of superconductivity hinges on three separate new ingredients: (a) treatment of Cooper pairs as real bosons, (b) inclusion of
Experimental realization of BCS-BEC crossover physics with a Fermi gas of atoms
This thesis presents experiments probing physics in the crossover between BoseEinstein condensation (BEC) and BCS superconductivity using an ultracold gas of atomic fermions. Scattering resonances in
Pseudogap 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
Experimental Realization of the BCS-BEC Crossover with a Fermi Gas of Atoms
Abstract Ultracold atomic gases have proven to be remarkable model systems for exploring quantum mechanical phenomena. Experimental work on gases of fermionic atoms in particular has seen astounding
Interacting Fermi gases and Bose-Fermi mixtures in optical lattices
Interacting fermionic quantum gases form the basis of solid state physics. In this thesis we choose a novel approach to explore such systems by creating quantum degenerate atomic Fermi gases and


Creation of ultracold molecules from a Fermi gas of atoms
The creation and quantitative characterization of ultracold 40K2 molecules is reported, which can be converted back to atoms by reversing the scan, and the small binding energy of the molecules is controlled by detuning the magnetic field away from the Feshbach resonance, and can be varied over a wide range.
Atom–molecule coherence in a Bose–Einstein condensate
The oscillation frequency is in excellent agreement with the theoretical molecular binding energy, indicating that the author has created a quantum superposition of atoms and diatomic molecules—two chemically different species.
Superfluid transition temperature in a trapped gas of Fermi atoms with a Feshbach resonance
We investigate strong-coupling effects on the superfluid phase transition in a gas of Fermi atoms with a Feshbach resonance. The Feshbach resonance describes a composite quasiboson that can give rise
Achieving a BCS transition in an atomic Fermi gas.
It is shown that, by adiabatically tuning the scattering length a from positive to negative values, one may transform the molecular Bose-Einstein condensate into a highly degenerate atomic Fermi gas, with the ratio of temperature to Fermani temperature T/T(F) approximately 10(-2).
Prospect of creating a composite Fermi–Bose superfluid
Abstract We show that composite Fermi–Bose superfluids can be created in cold-atom traps by employing a Feshbach resonance or coherent photoassociation. The bosonic molecular condensate created in
Resonance theory of the crossover from Bardeen-Cooper-Schrieffer superfluidity to Bose-Einstein condensation in a dilute Fermi gas
We present a description of the behavior of a superfluid gas of fermions in the presence of a Feshbach resonance over the complete range of magnetic field detunings. Starting from a resonance
Bose-Einstein condensation
In 1924 the Indian physicist Satyendra Nath Bose sent Einstein a paper in which he derived the Planck law for black-body radiation by treating the photons as a gas of identical particles. Einstein
Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor
A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled and exhibited a nonthermal, anisotropic velocity distribution expected of the minimum-energy quantum state of the magnetic trap in contrast to the isotropic, thermal velocity distribution observed in the broad uncondensed fraction.
Measurement of positive and negative scattering lengths in a Fermi gas of atoms.
Measurements of both large positive and large negative scattering lengths in a quantum degenerate Fermi gas of atoms near a magnetic-field Feshbach resonance find that anisotropic expansion of the gas can be attributed to a purely collisional effect.
Resonance superfluidity in a quantum degenerate Fermi gas.
For achievable experimental conditions, the transition to a superfluid phase is possible at the high critical temperature of about 0.5T(F).
