We present physica, a Mathematica package for the symbolic calculation of tree order processes. Originally physica was developed for the calculation of the total cross ...

The exact diagonalization method using a spin-adapted basis is employed to calculate the electronic structure of a multi-electron quantum dot. By isolating spin and orbital ...

This lesson includes exercises covering the following topics: Calculation of pH (Calculs de pH) Chemical kinetics (Cinétique chimique) Harmonic oscillator -- Schrodinger ...

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

This paper presents a new technique for achieving spectral accuracy and fast computational performance in a class of black hole perturbation and gravitational self-force ...

Mathematica gives us a very useful and simple way to visualize Molecular Dynamics (MD) simulations. Mathematica is used to animate the motion of ions from the results of MD ...

The present paper constitutes a development of our previous work devoted to calculations of the angular Fock coefficients ψk,p(α,θ). Explicit analytic ...

It is known that a lot of mathematical calculations must be processed during the practical use of exact and approximate methods that are designed to analyze different ...

VECTAN is a Mathematica package for doing calculations of vector analysis. It can be applied to manipulate expressions which are built from vector fields and functions by ...

An alternative method is proposed to calculate light bending and time delay in weak and strong gravitational fields. This approach is elementary, straightforward and uses ...
