Debian Science Physics packages

ABINIT is a package whose main program allows one to find the total energy, charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within Density Functional Theory (DFT), using pseudopotentials and a planewave basis.

ABINIT also includes options to optimize the geometry according to the DFT forces and stresses, or to perform molecular dynamics simulations using these forces, or to generate dynamical matrices, Born effective charges, and dielectric tensors. Excited states can be computed within the Time-Dependent Density Functional Theory (for molecules), or within Many-Body Perturbation Theory (the GW approximation). In addition to the main ABINIT code, different utility programs are provided.

This package contains the executables needed to perform calculations (however, pseudopotentials are not supplied). For a set of pseudopotentials, install the abinit-data package.

• Quantum Transport ;
• Time-resolved Spectroscopy ;
• Photo-emission Spectroscopy ;
• Vibrational Spectroscopy ;
• X-Rays Spectroscopy.

To allow the adoption of its recommendations about standardization, the ETSF proposes different libraries and tools implementing or using these specifications, as well as widely usable pieces of software.

FeynMF is a LaTeX package for easy drawing of professional-quality Feynman diagrams, illustrations that depict the fundamental interactions of subatomic particles. The diagrams may be created using either the Metafont or MetaPost programs. FeynMF lays out most diagrams satisfactorily from the structure of the graph without any need for manual intervention. Nevertheless all the power of Metafont or MetaPost is available for more obscure cases.

Note that you will need the texlive-metapost package in order to use the MetaPost-based version of FeynMF.

Fityk is a flexible and portable program for nonlinear fitting of analytical functions (especially peak-shaped) to data (usually experimental data). In other words, for nonlinear peak separation and analysis.

It was developed for analyzing diffraction patterns, but can be also used in other fields, since concepts and operations specific for crystallography are separated from the rest of the program.

Fityk offers various nonlinear fitting methods, subtracting background, calibrating data, easy placement of peaks and changing peak parameters, automation of common tasks with scripts, and much more. The main advantage of the program is flexibility - parameters of peaks can be arbitrarily bound to each other, eg. the width of a peak can be an independent variable, can be the same as the width of another peak or can be given by a complicated - common to all peaks - formula.

libjs-sphinxdoc is necessary for the Javascript stuff in the documentation.

GEANT is a framework for simulating the passage of subatomic particles through matter, for instance, particle detectors. For maximum flexibility, GEANT simulations are performed by linking FORTRAN code supplied by the user with the GEANT library, then running the resulting executable.
