Observation of a Strongly Interacting Degenerate Fermi Gas of Atoms
We report on the observation of a highly degenerate, strongly interacting Fermi gas of atoms. Fermionic lithium-6 atoms in an optical trap are evaporatively cooled to degeneracy using a magnetic… Expand
Universal Quantum Viscosity in a Unitary Fermi Gas
Viscosity studies of an ultracold gas of 6Li atoms in two temperature regimes enable comparison with a string theory limit. A Fermi gas of atoms with resonant interactions is predicted to obey… Expand
Scaling laws for evaporative cooling in time-dependent optical traps
We derive scaling laws for the number of atoms, collision rate, and phase-space density as a function of trap depth for evaporative cooling in an adiabadically lowered optical trap. The results are… Expand
Chemistry of the subalkalic silicic obsidians
Introduction The data bank Description and geographical distribution of analyzed Analytical techniques Major-element analyses X-ray fluorescence analyses Instrumental neutron-activation analyses… Expand
DDE remediation and degradation.
DDT and its metabolites, DDD and DDE, have been shown to be recalcitrant to degradation. The parent compound, DDT, was used extensively worldwide starting in 1939 and was banned in the United States… Expand

We have measured the heat capacity of an optically trapped, strongly interacting Fermi gas of atoms. A precise addition of energy to the gas is followed by single-parameter thermometry, which… Expand
Dynamics of noise-induced heating in atom traps
A Fokker-Planck equation is derived for the energy distribution of atoms in a three-dimensional harmonic trap with fluctuations in the spring constant and the equilibrium position. Using this model,… Expand

The main objective of this study was to determine the influence of soil moisture, organic matter amendment and plastic cover (a virtually impermeable film, VIF) on diffusion and emissions of (Z)- and… Expand
Distribution in Australia and Seed Transmission of Tobacco streak virus in Parthenium hysterophorus.
Tobacco streak virus (TSV) was found to commonly occur in Parthenium hysterophorus, as symptomless infections, in central Queensland, Australia across a large area infested with this weed. Several… Expand
Thermodynamic Measurements in a Strongly Interacting Fermi Gas
Strongly interacting Fermi gases provide a clean and controllable laboratory system for modeling strong interparticle interactions between fermions in nature, from high temperature superconductors to… Expand
