It is shown how the time-dependent Schr\"{o}dinger equation may be simply derived from the dynamical postulate of Feynman's path integral formulation of quantum mechanics and the Hamilton-Jacobi equat...
A stochastic theory for a branching process in a neutron population with two energy levels is used to assess the applicability of the differential self-interrogation Feynman-alpha method by numericall...
We discuss the duality theorem, which provides a relation between loop integrals and phase space integrals. We rederive the duality relation for the one-loop case and extend it to two and higher-order...
The classical notions of continuity and mechanical causality are left in order to refor- mulate the Quantum Theory starting from two principles: I) the intrinsic randomness of quantum process at micr...
We present an algorithm that reveals relevant contributions in non-threshold-type asymptotic expansion of Feynman integrals about a small parameter. It is shown that the problem reduces to finding a c...
Given a Feynman parameter integral, depending on a single discrete variable $N$ and a real parameter $\epsilon$, we discuss a new algorithmic framework to compute the first coefficients of its Lauren...

General formula for symmetry factors of Feynman diagrams with fields having higher spin is derived. By pointing out that any fields can be treated just as scalar fields (real or complex) then symmetr...
The physical model (PhsMdl) of a nonrelativistic quantized Schrodinger’s electron (SchrEl) is offered. The behaviour of the SchrEl’s well spread (WllSpr) elementary electric charge (ElmElcChrg) had ...
In this paper we study the quantum wave packet and the Feynman-de Broglie-Bohm propagator of the linearized Schuch-Chung-Hartmann equation along a classical trajetory.
The Feynman integral is one of the most accurate methods for calculating density operator dy- namics in open quantum systems. However, the number of time steps that can realistically be used is alway...
The Nobel Prize in Physics 1965, Richard P. Feynman, for the fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles.
基于Green函数的相空间生成泛函,导出了广义正则Ward恒等式.指出无须作出相空间生成泛函中对正则动量的路径积分,即可求得树图近似下的Feynman规则.对场的拉氏量添加一个四维散度项后,场的传播子发生了改变.
在正态模糊格点费米子方案中,一个合理的自洽的Fourier变换显示了动量空间中周期性的破缺,从而避免了多余的费米子模.本文并讨论了弱耦合极限下模糊格点的费曼规则,计算了轴矢流反常的单圈微扰结果,获得了标准的Adler-Bell-Jackiw手征反常项.
