Post-Wick theorems for symbolic manipulation of second-quantized expressions
Manipulating expressions in many-body perturbation theory becomes unwieldy with increasing order of the perturbation theory. Here I derive a set of theorems for efficient simplification of such expressions. The derived rules are specifically designed for implementing with symbolic algebra tools. As an illustration, we count the numbers of Brueckner–Goldstone diagrams in the first several orders...
متن کاملQuaternions: A Mathematica Package for Quaternionic Analysis
This paper describes new issues of the Mathematica standard package Quaternions for implementing Hamilton’s Quaternion Algebra. This work attempts to endow the original package with the ability to perform operations on symbolic expressions involving quaternion-valued functions. A collection of new functions is introduced in order to provide basic mathematical tools necessary for dealing with re...
متن کاملSymbolic Algebra and Renormalization of Gauge Theories
Symbolic algebra relevant to the renormalization of gauge theories can be efficiently performed by machine using modern packages. We devise a scheme for representing and manipulating the objects involved in perturbative calculations of gauge theories. This scheme is readily implemented using the general purpose package , Mathematica. The techniques discussed are used to calculate renormalizatio...
متن کاملModern Techniques for One-Loop Calculations
We review the techniques used for one-loop calculations with emphasis on practical applications. QED is used as an example but the methods can be used in any theory. The aim is to teach how to use modern techniques, like the symbolic package FeynCalc for Mathematica and the numerical package LoopTools for Fortran or C++, in one-loop calculations.
متن کاملSymbolic Maximum Likelihood Estimation with Mathematica
Mathematica is a symbolic programming language that empowers the user to undertake complicated algebraic tasks. One such task is the derivation of maximum likelihood estimators, demonstrably an important topic in statistics at both the research and the expository level. In this paper, a Mathematica package is provided that contains a function entitled SuperLog. This function utilizes pattern-ma...
