In this paper the quantum hyperbolic equation formulated in our earlier paper [Found. Phys. Lett.

propagation depends on the barrier height. The Planck wall potential is introduced,V

A singular perturbation theory is applied to the FitzHugh-Nagumo nerve conduction equation with quadratic nonlinearity to obtain travelling pulse profiles. Starting with the zeroth-order pulse solution, the explicit first-order correction to the propagating pulses is obtained. 相似文献

We prove the existence of a set of initial data to which correspond solutions of the nonlinear Klein-Gordon equation with a polynomial nonlinear term, which converge asymptotically, when t→+∞, to solutions of the linear Klein-Gordon equation. 相似文献

We present here a mathematical explanation of how the Schr?dinger equation for a class of harmonic oscillators possesses exact

A trajectory interpretation is developed for the Klein-Gordon equation in one dimension. The development is couched in a Hamilton-Jacobi representation. Equations of motion are developed. Different trajectories for a given eigenvalue energy are shown to manifest different microstates of the eigenfunction of that particular energy. 相似文献

Using our previously developed theory, we prove the main conclusions of scattering theory for the Klein-Gordon equation under hypotheses weaker than presently known. We consider more general equations and obtain stronger results. 相似文献

量子电动力学认为库仑力是电荷之间交换虚光子的结果,最有力的证据是从虚光子假说直接推出库仑势能.克莱因-戈登方程(□2-m2)Φ(x,t)=0是一个用来描述质量为m,自旋为0,电荷为0的标量场的场方程,虚光子可以用粒子静止质量为0的标量场描述,因此满足克莱因-戈登方程□2Φ(x,t)=0.本文利用克莱因-戈登方程推导两质子之间的库仑势. 相似文献

We obtain a hyperbolic equation whose discontinuity waves are all exceptional and propagate with velocity λ. When λ → ∞ or λ=c, this equation becomes identical to the Schrödinger equation and to the Klein-Gordon equation respectively. We also show that λ is related to the dispersion relationE(p). 相似文献

We investigate bound states of a composite system consisting of a charged particle orbiting a neutral, stationary magnetic dipole. We find all bound states are metastable and none exist with angular momentum less than eleven. Our calculations is performed in two space dimensions. 相似文献

The virial theorem for the Klein-Gordon equation has been generalized with respect to non-integrable scale-invariant probe functions. Ground-state energies as well as certain upper bounds on the coupling constants have been established. For definiteness several kinds of attractive power potentials have been considered. 相似文献

The Klein-Gordon equation is studied in a family of exact solutions of the Einstein equations whose material content is a perfect fluid with stiff equation of state (p=). The field equations are solved exactly for some members of the family and for massive or massless fields. 相似文献

A consistent causal interpretation of the Klein-Gordon equation treated as a field equation has been developed, and leads to a model of entities described by the Klein-Gordon equation, i.e., spinless, massive bosons, as objectively existing fields. The question arises, however, as to whether a causal interpretation based on a particle ontology of the Klein-Gordon equation is also possible. Our purpose in this article will be to indicate, by making what we believe is a best possible attempt at developing a particle interpretation of the Klein-Gordon equation, that such an interpretation is untenable. To resolve the nonpositive-definite probability density difficulties with the Klein-Gordon equation, we modify this equation by the introduction of an evolution parameter. We base our subsequent considerations on this modified Klein-Gordon equation. Partly to motivate the need for a relativistic causal interpretation and partly to give emphasis to aspects of the causal interpretation often overlooked, we begin our article with a brief historical survey of the causal interpretation.Other work commitments prevented publication of this article in the special issue ofFoundations of Physics in honor of Prof. J. P. Vigier. I would nevertheless like to dedicate this work to Prof. Vigier in recognition of this untiring contributions to the causal interpretation in particular and to the foundations of physics in general. I take this opportunity to thank Prof. Vigier for his help during my Royal Society fellowship spent at the Institut Henri Poincaré in the academic year 1988–1989. 相似文献
