Abstract
We propose an efficient mechanism for the evaporative cooling of trapped fe rmions directly into quantum degeneracy. Our idea is based on an electric f ield induced elastic interaction between trapped atoms in spin symmetric st ates. We discuss some novel general features of fermionic evaporative cooli ng and present numerical studies demonstrating the feasibility for the cool ing of alkali-metal fermionic species Li-6, K-40, and Rb-82.84.86. We also discuss the sympathetic cooling of fermionic hyperfine spin mixtures, inclu ding the effects of anisotropic interactions.
