Renormalization Of The Energy-Momentum Tensor And The Validity Of The Equivalence Principle At Finite Temperature, Jf Donoghue, Br Holstein, Rw Robinett Dec 1984

Renormalization Of The Energy-Momentum Tensor And The Validity Of The Equivalence Principle At Finite Temperature, Jf Donoghue, Br Holstein, Rw Robinett

Barry R Holstein

Using the techniques of finite-temperature field theory we renormalize the electromagnetic and gravitational couplings of an electron which is immersed in a heat bath with T


Guage Invariant De Gennes Model, Anthony Day, T. Lubensky Jun 1984

Guage Invariant De Gennes Model, Anthony Day, T. Lubensky

Anthony Roy Day

A gauge-invariant formulation of the de Gennes model for the nematic—to—smectic-A transition is presented. In this formulation the energy associated with the gauge field A⃗ reduces to the Frank elastic energy with the application of the constraint n⃗0·A⃗=0 where n⃗0 is the uniform equilibrium director and A⃗ is to be identified with deviations δn⃗ of the director from equilibrium. It is shown that thermodynamic quantities and renormalization-group recursion relations are gauge invariant. All gauge dependence appears in the exponent η describing order-parameter correlations. The gauge invariance of a negative dielectric anisotropy smectic-A in an external electric field is also studied.

An Artin Relation (Mod 2) For Finite Group Actions On Spheres, Ronald M. Dotzel Jan 1984

An Artin Relation (Mod 2) For Finite Group Actions On Spheres, Ronald M. Dotzel

Ronald Dotzel

Recently it has been shown that whenever a finite group G (not a /7-group) acts on a homotopy sphere there is no general numerical relation which holds between the various formal dimensions of the fixed sets of ^-subgroups (p dividing the order of (7). However, if G is dihedral of order 2q (q an odd prime power) there is a numerical relation which holds (mod 2). In this paper, actions of groups G which are extensions of an odd order /?-group by a cyclic 2-group are considered and a numerical relation (mod 2) is found to be satisfied (for such …

Possibilities For Finite Grand Unification With N = 2 Supersymmetry, Asim Gangopadhyaya Dec 1983

Possibilities For Finite Grand Unification With N = 2 Supersymmetry, Asim Gangopadhyaya

Asim Gangopadhyaya

We study the prospects for constructing finite grand unified theories using softly broken N = 2 global supersymmetry. The requirement that the supersymmetry breaking scale be of order 103−104 GeV and that the mixing between the observed light fermions and the mirror fermions present in N = 2 theories be small («mW), make it difficult to construct finite grand unified theories based on a large class of simple groups with a realistic symmetry breaking pattern.

Topoi And Categories Of Fuzzy Sets, Lawrence Stout Dec 1983

Topoi And Categories Of Fuzzy Sets, Lawrence Stout

Lawrence N. Stout

Let H be a completely distributive lattice and hence a Heyting algebra. Goguen's category of fuzzy sets Set(H) Eytan's logos Fuz(H) and the topos of sheaves on H, Sh(H), are interconnected by pairs of adjoint functors between them. Each of the categories has a predicate calculus. These predicate calculi are related through the functors between the categories. Change of base lattice gives rise to several functors which preserve or reflect specific kinds of statements in the predicate calculi. This paper gives details of the categories, the predicate calculi attached to them, the functors between the categories, and the preservation properties …


Predicting The Proton Mass From Pi-Pi-Scattering Data, Jf Donoghue, E Golowich, Br Holstein Dec 1983

Predicting The Proton Mass From Pi-Pi-Scattering Data, Jf Donoghue, E Golowich, Br Holstein

Barry R Holstein

We relate experimental information on ππ scattering to tree-level effective chiral Lagrangians. The result is of a form similar to that used in Skyrme-type models of the proton, where the nucleons are described as topologically stable solitons of the chiral fields. In such models, one can express the proton mass in terms of measured scattering data, with the result Mp=880±300 MeV. We interpret this as a consistency test for the Skyrme models.

Nonergodicity In Path Integral Molecular Dynamics, Randall W. Hall, B. J. Berne Dec 1983

Nonergodicity In Path Integral Molecular Dynamics, Randall W. Hall, B. J. Berne

Randall W. Hall

Molecular dynamics can be used to evaluate the path integral representation of the density matrix. Implicit in this method is the assumption that the dynamical system is ergodic. It is shown here that this is not the case in many systems that are of interest. For example water or liquid neon can not be simulated by this method. Monte Carlo methods do not suffer from this weakness.


A Path Integral Monte Carlo Study Of Liquid Neon And The Quantum Effective Pair Potential, Devarajan Thirumalai, Randall W. Hall, Bruce J. Berne Dec 1983

A Path Integral Monte Carlo Study Of Liquid Neon And The Quantum Effective Pair Potential, Devarajan Thirumalai, Randall W. Hall, Bruce J. Berne

Randall W. Hall

The path integral Monte Carlo (PIMC) method is used to simulate liquid neon at T=40 K. It is shown that quantum effects are not negligible and that when the quantum effective pair potential is used in a classical molecular dynamics simulation the results obtained for the radial distribution function agrees with that predicted by a full path integral Monte Carlo simulation. The validity of this procedure is further shown by comparing the results obtained by this method to experimental measurements of liquid neon at T=35 K.

Maximal Functions Measuring Smoothness, Ronald A. Devore, Robert C. Sharpley Dec 1983

Maximal Functions Measuring Smoothness, Ronald A. Devore, Robert C. Sharpley

Robert Sharpley

Maximal functions which measure the smoothness of a function are introduced and studied from the point of view of their relationship to classical smoothness and their use in proving embedding theorems, extension theorems and various results on differentiation. New spaces of functions which generalize Sobolev spaces are introduced.
