The Los Alamos Solid-State Optical Refrigerator
Optical refrigeration may provide the physical basis for solid-state cryocooling. Devices based on this physics would be vibrationless, compact, and free of electromagnetic interference. Having no moving parts and being pumped by a diode lasers, optical refrigerators would be rugged with operating lifetimes of years. Experiments at Los Alamos National Laboratory have demonstrated the basic phys...

We review the WN algebra and its quantum deformation, based on free field realizations. The (quantum deformed) WN algebra is defined through the (quantum deformed) Miura transformation, and its singular vectors realize the Jack (Macdonald) polynomials.

The well known phenomenological theory of F. and H. London leads to rather severe restrictions for the electronic wave functions which might possibly account for the phenomenon of superconductivity. Yet all attempts to construct such wave functions according to the principle of quantum mechanics have been so far unsuccessful. This failure seems to stem from the use of one-electron functions for...

The application of symmetry considerations to the theory of superconductivity has been considered further. The problem consists of extending the methods recently advanced (1) so as to include the interaction of the electrons with the lattice vibrations. (See Quarterly Progress Report, April 15, 1951.) It now appears that the difficulties which have been blocking progress are not of a formal mat...
متن کاملSolid State Physics
By definition, solid state is that particular aggregation form of matter characterized by strong interaction forces between constituent particles (atoms, ions, or molecules). As a result, a solid state material has an independent geometric form (in contrast to liquids, which take the form of the container) and an invariant volume (in contrast to gases/vapors) in given temperature and pressure c...
