We present a recursive diagrammatic method for evaluating tree-level Feynman diagrams involving multi-fermions which interact through gauge bosons (gluons or photons). Based ...

In the present investigation, the characteristics of the integrated inner product calculation as a function of Doppler frequency present in signal analysis have been ...

A fast and robust time-independent method to calculate thermal rate constants in the deep resonant tunneling regime for scattering reactions is presented. The method is based ...

Polynomial formulae for the Witten invariant of 3-manifolds for manifolds which bound plumbed 4-manifolds are developed via the combinatorial approach of Lickorish. A number ...

Modern technical computing environments, such as Mathematica or Matlab, provide powerful tools and techniques for research reactor analysis combined with advanced graphical ...

The Hartree-Fock method for calculating the electronic structure of N-electron quantum dot systems was implemented in Mathematica using an easily-understood modular code. ...

We present the computer program FeynCalc for automatic algebraic calculation of Feynman amplitudes. The purpose of the package is to facilitate the process of calculating ...

We present an exact calculation of the single-electron energies and wave-functions for any bound state in a realistic Si-SiO2 spherical quantum dot, including the material ...

A Mathematica package for color summed calculations in QCD (SU(Nc)) is presented. Color contractions of any color amplitude appearing in QCD may be performed, and the package ...

This paper is devoted to the symbolic calculation of the scattering coefficient in diffraction by a circular disk, by the use of Mathematica. Three diffraction problems are ...
