In this note we report on the new version of FeynCalc, a Mathematica package for symbolic semiautomatic evaluation of Feynman diagrams and algebraic expressions in quantum ...

The Sitnikov problem is one of the most simple cases of the elliptic restricted three body system. A massless body oscillates along a line (z) perpendicular to a plane (x, y) ...

A general method for approximate solution of one-dimensional Schrödinger equations with a wide range of square-integrable potentials is described. The potential is expanded ...

This article describes three Mathematica packages for the automatic calculation of one-loop Feynman diagrams: the diagrams are generated with FeynArts, algebraically ...

We present extensions to the computer algebra and multimedia environment Mathematica to enable students to investigate signal processing theory. Students interact with the ...

In this paper we give a comuter proof of a new polynomial identity, which extends a recent result of Alladi and the first author. In addition, we rovide computer proofs for ...

An analytical evaluation of matrix elements of single spin operators in tetranuclear mixed-valence metal clusters is presented. The case of a ground state of the cluster with ...

Applying the higher-order averaging method, we study the periodically forced, standard Duffing oscillator. A package of the computer algebra system, Mathematica, recently ...

General expressions for matrix elements of the electric multipole operators in axial and triaxial harmonic oscillator basis are given. In each case we present algorithms ...

Asking questions, gathering and analyzing data, recognizing patterns and interrelationships, and forming conclusions are certainly important activities in which students of ...
