Mapping out spin and particle conductances in a quantum point contact.

We study particle and spin transport in a single-mode quantum point contact, using a charge neutral, quantum degenerate Fermi gas with tunable, attractive interactions. This yields the spin and particle conductance of the point contact as a function of chemical potential or confinement. The measurements cover a regime from weak attraction, where quantized conductance is observed, to the resonantly interacting superfluid.

A thermoelectric heat engine with ultracold atoms.

Thermoelectric effects, such as the generation of a particle current by a temperature gradient, have their origin in a reversible coupling between heat and particle flows. These effects are fundamental probes for materials and have applications to cooling and power generation. Here, we demonstrate thermoelectricity in a fermionic cold atoms channel in the ballistic and diffusive regimes, connected to two reservoirs.

A descriptive analysis of personality and gender at the Louisiana State University School of Veterinary Medicine.

The goals of this study were to explore the Myers-Briggs Type Indicator profile and gender differences of Louisiana State University veterinary students. A 12-year composite sample (N = 935) revealed that the personality profile was different from the published US population norm, but similar to the bimodal ESTJ-ISTJ profile found in Louisiana medical students. Significant gender differences were found among six of the 16 types.
