State selective cooling of SU(N) Fermi gases

چکیده

We investigate a species selective cooling process of trapped $\mathrm{SU}(N)$ Fermi gas using entropy redistribution during adiabatic loading an optical lattice. Using high-temperature expansion the Hubbard model, we show that when subset $N_A < N$ single-atom levels experiences stronger trapping potential in certain region space, dimple, it leads to improvement as compared $\mathrm{SU}(N_A)$ only. optimal performance is achieved all atomic experience same outside dimple and quantify for various $N_A$ by evaluating dependence final densities temperatures functions initial entropy. Furthermore, considering ${}^{87}{\rm Sr}$ ${}^{173}{\rm Yb}$ specificity, provide quantitative discussion how state can be with readily available experimental techniques.

Ground-state pressure of quasi-2D Fermi and Bose gases.

Using an ultracold gas of atoms, we have realized a quasi-two-dimensional Fermi system with widely tunable s-wave interactions nearly in a ground state. Pressure and density are measured. The experiment covers physically different regimes: weakly and strongly attractive Fermi gases and a Bose gas of tightly bound pairs of fermions. In the Fermi regime of weak interactions, the pressure is syste...

Unitary polarized Fermi gases

— Although recent theoretical and experimental progress have considerably clarified pairing mechanisms in spin 1/2 fermionic superfluid with equally populated internal states, many open questions remain when the two spin populations are mismatched. We show here that, taking advantage of the universal behavior characterizing the regime of infinite scattering length, the macroscopic properties of...

Trapped Fermi gases

Trapped degenerate atomic gases provide exciting opportunities for the manipulation and quantitative study of quantum statistical effects, such as the strikingly direct observation of Bose-Einstein condensation @1–3#. Although perhaps not as dramatic as the phase transition associated with bosons, the behavior of trapped Fermi gases also merits attention, both as a degenerate quantum system in ...

Polarized Fermi gases

Recently, two experiments, reported in Science[1, 2], have studied a polarized ultra-cold degenerate Fermi gas. This is a very new area that has attracted a great amount of interest from widely varying fields ranging from condensed matter physics, atomic molecular and optical physics, to particle and astro physics. As polarized Fermi gases have been demonstrated to be stable near the resonance,...

Trapped Atomic Fermi Gases

A many-body system of fermion atoms with a model interaction characterized by the scattering length a is considered. We treat both a and the density as parameters assuming that the system can be created artificially in a trap. If a is negative the system becomes strongly correlated at densities ρ ∼ |a| −3 , provided the scattering length is the dominant parameter of the problem. It means that w...
