Field-theoretical Description of High-,, Superconductors: Topological Excitations, Generalized Statspace-time. The interest in this kind of theory was, to a large degree, generated by the recent discovery of substances which become superconductors at a temperature quite a bit higher than the old BCS-type materials.. The reason for this unexpected connection between areas of physics which at first

Random Dynamics, Three Generations, and Skewness,sent a project which I and others have worked on for several years.. We seek to derive the already known laws of nature as a result of almost any very complicated fundamental model. In the second talk we look at the Standard Model—especially the structure of the gauge group—and, inspired by that, se

Gauge Anomalies in Two Dimensions,y and to outline the resultant interesting and unfamiliar features of such theories. As is well known, such anomalies are not special to two dimensions; they can occur in any number of dimensions where chiral fermions exist, and it was believed until a few years ago that in all such cases the gauge

Some Topics in Topological Quantum Field Theories,vo Lozano, Hugo Montani, and George Thompson. In the first part of the talk I will review some relevant features of topological field theory quantization. Then, in section 2, I will discuss the connection among various approaches to quantization by using a stochastic process description. In section

Microscopic and Macroscopic Loops in Nonperturbative Two-Dimensional Gravity,e correlation functions of operators in these models can also be easily computed. We distinguish between two kinds of operators, microscopic and macroscopic loops. By microscopic loops we mean expressions like Tr .. in the matrix models with . finite. They contain all the information about integrals over the surface of local operators.

Field-theoretical Description of High-,, Superconductors: Topological Excitations, Generalized Statf a layered structure consisting of CuO. planes in which Cu. ions are assembled on the nodes and O. ions on the links of a square lattice. There is experimental evidence that the superconducting properties are highly anisotropic and the planar nature of the system, it has been argued, plays a key role in the mechanism of superconductivity.

Fractional Statistics in Quantum Mechanics,, . = π/2, seems to make no sense because iterating Eq. (1) twice gives.and the single-valuedness of Ψ demands that e^{2iemptyset }= 1, so one concludes that Bose and Fermi statistics exhaust all the allowed values of ..
