We measure radio-frequency spectra for a two-component mixture of a 6Li atomic Fermi gas in a quasi-two-dimensional regime with the Fermi energy comparable to the energy level spacing in the tightly confining potential. Near the Feshbach resonance, we find that the observed resonances do not correspond to transitions between confinement-induced dimers. The spectral shifts can be fit by assuming...

We study the perturbative correction to the ground state energy eigenvalue of a 2-dimensional dilute fermi gas with weak short-range two body repulsion. From the structure of the energy shift we infer the presence of an induced two body long range repulsive interaction 1 r 2 among the constituent electrons indicating a potential instability of the fermi liquid ground state.

We review the non-Fermi or marginal liquid behavior of a relativistic QED plasma. In this medium a quasiparticle has a damping rate that depends linearly on the distance between its energy and the Fermi surface. We stress that this dependence is due to the long-range character of the magnetic interactions in the medium. Finally, we study how the quark damping rate modifies the gap equation of c...

We study the conductance of carbon nanotube wires in the presence of disorder, in the limit of phase coherent transport. For this purpose, we have developed a simple numerical procedure to compute transmission through carbon nanotubes and related structures. Two models of disorder are considered, weak uniform disorder and isolated strong scatterers. In the case of weak uniform disorder, our sim...

We prove a perturbative inversion theorem for the map between the interacting and the noninteracting Fermi surface for a class of many fermion systems with strictly convex Fermi surfaces and short-range interactions between the fermions. This theorem gives a physical meaning to the counterterm function K that we use in the renormalization of these models: K can be identified as that part of the...

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 quasi-Boson, which can give rise to an additional pair-ing interaction between the Fermi atoms. This attractive interaction becomes stronger as the threshold energy (2ν) of the Feshbach resonance two-particle bound state is low...

The Fermi Gamma-Ray Space Telescope, successfully launched on June 11th, 2008, is the next generation satellite experiment for high-energy gamma-ray astronomy. The main instrument, the Fermi Large Area Telescope (LAT), with a wide field of view (> 2 sr), a large effective area (> 8000 cm2 at 1 GeV), sub-arcminute source localization, a large energy range (20 MeV 300 GeV) and a good energy resol...

This paper describes how the concepts of Charge Neutrality Level (CNL) and Induced Density of Interface States (IDIS) can successfully explain the energy level alignment at metal-organic and organic-organic interfaces. We propose that the CNL acts as an effective Fermi level for the organic semiconductor: its partial alignment with the metal Fermi level (in the case of metal-organic interfaces)...

AbstractHydrogen-bond kinetics plays an important role in the establishment of the transport properties of water. In this paper we propose to consider protons in water as a Fermi gas. We use Fermi statistics to determine the Fermi energy, the averaged time between collisions of the protons, and the speed of sound in liquid water. This time is also used to interpret the response in frequency of ...

The thermodynamics for a system with given temperature, density, and volume is described by the Canonical ensemble. The thermodynamics for a corresponding system with the same temperature, volume, and average density is described by the Grand Canonical ensemble. In general, a chosen thermodynamic potential (e.g., free energy) is different in the two cases. Their relationship is considered here ...
