Poking at the correspondence principle with derivative couplings
نویسنده
چکیده
It is shown that quantum mechanical systems obtained from a heuristic path integral quantization of lagrangians of the form L = ∑ n 1 n! fn(q)q̇ n violate in general the correspondence principle, unless L is not more than quadratic in q̇. The field theoretic counterpart of this result and its consequence on models of interacting scalar and vector fields and particularly the electroweak interactions, are briefly discussed. address after Oct. 93, SLAC, P.O.Box 4349, Stanford, CA. 94309. 0

The Dynamic and Vibration Response of Composite Cylindrical Shell Under Thermal Shock and Mild Heat Field
In this article, the vibration and dynamic response of an orthotropic composite cylindrical shell under thermal shock loading and thermal field have been investigated. The problem is that the shell is initially located at a first temperature, and some tension caused by a mild heat field is created, then the surface temperature of the cylinder suddenly increases. The partial derivative equations...
متن کاملConformal Symmetry as a Template for QCD∗
Conformal symmetry is broken in physical QCD; nevertheless, one can use conformal symmetry as a template, systematically correcting for its nonzero β function as well as higher-twist effects. For example, commensurate scale relations which relate QCD observables to each other, such as the generalized Crewther relation, have no renormalization scale or scheme ambiguity and retain a convergent pe...
متن کاملEmission rates, the Correspondence Principle and the Information Paradox
When we vary the moduli of a compactification it may become entropically favourable at some point for a state of branes and strings to rearrange itself into a new configuration. We observe that for the elementary string with two large charges such a rearrangement happens at the ‘correspondence point’ where the string becomes a black hole. For smaller couplings it is entropically favourable for ...
متن کاملModified mathematical model for variable fill fluid coupling
Variable fill fluid couplings are used in the speed control units. Also, variation in coupling oil volume is used in adapting one size of coupling to a wider range of power transmission applications. Available model for the partially filled fluid couplings, has a good performance for couplings with fixed amount of oil but their performance will be degraded if they are used for the variable fill...
متن کاملScale Relativity, Fractal Space-Time, and Quantum Mechanics
This paper describes the present state of an attempt at understanding the quantum behaviour of microphysics in terms of a nondifferentiable space-time continuum having fractal (i.e., scale-dependent) properties. The fundamental principle upon which we rely is that of scale relativity, which generalizes to scale transformations Einstein’s principle of relativity. After having related the fractal...
