Radiation-Induced Segregation: A Microchemical Gauge to Quantify Fundamental Defect Parameters

Gauge theories induced by bosons in fundamental representation

A lattice theory of scalar bosons in the fundamental representation of the gauge group SU(Nc) and of the global symmetry group SU(Nf) is shown to induce a standard gauge theory only at large Nf . The system is in a deconfined phase at strong scalar self-coupling and any finite Nf . The requirement of convergence of the effective gauge action imposes a lower limit on the scalar mass.

Solution of gauge theories induced by fundamental representation scalars

Gauge theories induced by scalars in the fundamental representation of the U(Nc)gauge×U(Nf )global group are investigated in the large Nc and Nf limit. A master field is defined from bilinears of the scalar field following an Eguchi-Kawai type reduction of spacetime. The density function for the master field satisfies an integral equation that can be solved exactly in two dimensions (D = 2) and...

Radiation-induced Segregation and Void Swelling in 304 Stainless Steel

. Void swelling and radiation-induced segregation have been measured in 304 stainless steel. Samples were irradiated in the outer regions of the EBR-11reactor where displacement rates of 2.OX10-8and 6.6 xl 0-8dpds are comparable to those in pressurized water reactor components. Samples were inadiated at temperatures from 371-390°C to total doses of up to 20 dpa. Void swelling reached a maximum ...

We study all possible weak limits of a minimizing sequence, for p-energy functionals, consisting of continuous maps between Riemannian manifolds subject to a Dirichlet boundary condition or a homotopy condition. We show that if p is not an integer, then any such weak limit is a strong limit and, in particular, a stationary p-harmonic map which is C 1;; continuous away from a closed subset of th...
