Vector Mean Field Theory of Statistics,ractional statistics.. One way to think of statistics is by reference to the phase .. which develops when two identical particles are exchanged. For bosons . = 0 and for fermions . = π. In 2 + 1 dimensions it turns out that . can take any value, and so particles with general . have been called anyon

Spinon-Holon Statistics, and Broken Statistical Symmetry for the t-J and Hubbard Models in 2D,hich the spin and charge degrees of freedom are decoupled; the excitations associated with the former are called spinons, and with the latter holons. The usual formulation for this model involves the author’s. auxiliary particles (slave bosons or fermions) and a mean-field approximation based upon a

Superconductive Tunneling in YBa2Cu3O7 Thin Films: Dependence upon Crystallographic Orientation, magnetron sputtering, as well as laser deposition. Films of orientations (001), (103) and (100) are then used in our tunneling experiments. Gap-like structures at 18meV are routinely and reproducibly seen when there is some . plane directed towards the film surface, i.e. in the following situations

Infrared Properties: The normal State, the Energy Gap, and the Temperature Dependence of the Gap, problem of understanding the origin of high T.. Here we discuss some of the contributions made by infrared measurements in this area. We emphasize reflectivity measurements of single domain Y.Ba.Cu.O. crystals, where one can distinguish between chain and plane contributions to the infrared conducti
