Fortran 95 programs which might be of interest to students


You may download the computer programs provided below and use them as you wish. However, it would be a violation of scientific ethical rules to modify these codes and re-distribute them without giving credit to the author of the original codes (Volker Oberacker). I have tested all codes thoroughly on both LINUX and Mac OS X platforms. Nevertheless, it should be understood that these programs are being offered to the physics community without any warranty whatsoever.

To implement the codes on your workstation, download the *.zip files from the links given below onto your computer and unzip the files in a new directory. You will find the Fortran 95 source file (*.f95), an instruction file (*.txt) which tells you how to compile and run the Fortran code, and a sample output file (*.out). The Fortran 95 source file contains comments and references. All codes have been compiled and tested with the open-source GNU Fortran compiler (gfortran) which is part of the GNU Compiler Collection (GCC). The gfortran compiler is available for all major platforms (LINUX, Mac OS X, Windows). Details can be found e.g. at this Website

Clebsch-Gordan coefficient programs

A function program which calculates Clebsch-Gordan coefficients. Two versions of the code are offered. The first version, cg1, calculates the CGs for several angular momentum quantum numbers and compares the output to known analytical answers.

Fortran 95 code:

The second version, cg2, is an INTERACTIVE code where you enter the angular momentum quantum numbers at the Terminal command line.

Fortran 95 code:

Runge-Kutta 4-step program

4-step Runge-Kutta subroutine, including a test program which solves Hamilton's equations for the 1-D harmonic oscillator.

Fortran 95 code:

Wigner's reduced rotation matrix d^j_mn (beta) program

A function program which computes Wigner's reduced rotation matrix from an analytical expression.

Fortran-95 code:

Spherical harmonics Y_lm (theta,phi) program

A subroutine which computes Y_lm using Wigner's reduced rotation matrix d^l_{m 0} (theta).

Fortran-95 code:
