0 Thermodynamics of Multi - Component Fermi Vapors
We study the thermodynamical properties of Fermi vapors confined in a harmonic external potential. In the case of the ideal Fermi gas, we compare exact density profiles with their semiclassical approximation in the conditions of recent experiments. Then, we consider the phase-separation of a multi-component Fermi vapor. In particular, we analyze the phase-separation as a function of temperature...
متن کاملFermi Liquid Theory: Thermodynamics
I have chosen to use a spin notation of “up” or “down” with respect to a convenient z axis rather than a more rotationally invariant formulation. The quantity εp is not the same as in the interacting system, but can be expanded in the same way about p = pF εp = εF + vF (p − pF )+ · · · (3) where εF , vF are not the same as in the noninteracting system. The single quasiparticle energy does not d...
متن کاملThermodynamics of an Attractive 2D Fermi Gas.
Thermodynamic properties of matter are conveniently expressed as functional relations between variables known as equations of state. Here we experimentally determine the compressibility, density, and pressure equations of state for an attractive 2D Fermi gas in the normal phase as a function of temperature and interaction strength. In 2D, interacting gases exhibit qualitatively different featur...
متن کاملUniversal Thermodynamics of a Strongly Interacting Fermi Gas
We study the properties of an optically-trapped, Fermi gas of Li atoms, near the center of a broad Feshbach resonance, where strong interactions are observed. Strongly interacting Fermi gases exhibit universal behavior, and are of interest as models of exotic systems ranging from high temperature superconductors to neutron stars and quark-gluon plasmas. We measure the frequency and damping rate...
متن کاملBranch-cut singularities in thermodynamics of Fermi liquid systems.
The recently measured spin susceptibility of the two-dimensional electron gas exhibits a strong dependence on temperature, which is incompatible with the standard Fermi liquid phenomenology. In this article, we show that the observed temperature behavior is inherent to ballistic two-dimensional electrons. Besides the single-particle and collective excitations, the thermodynamics of Fermi liquid...
