Codes and Useful Links

Some useful black boxes

  • relcom2labsystem.tar.gz A f90 package that generates both m-scheme and J-coupled TBMEs in the oscillator basis. We will discuss how to use this before the afternoon session on Thursday.
  • Some f90 subroutines (NOT a standalone code) from a larger code that calculates relative two-body matrix element $\langle nl|V|n'l\rangle$ of the Coulomb potential in the HO basis. The main purpose of this code is to illustrate the algorithm to calculate generalized Laguerre polynomials $L^{l+1/2}_n$ that enter the definition of the HO wf's $R_{nl}$. Here is the Makefile that was missing.

UPDATE: One of the files (renorm-modules.f90) in the TBME package had a subtle but important bug where matrix elements in the spin-triplet channel, which should vanish due to the structure of the Minnesota potential, were non-zero. Here is a fixed version of the file in question renorm-modules.f90.gz.

  • C++ code adapted from Dick Furnstahl's Computational Physics course at Ohio State to calculate the Coulomb hamiltonian on a HO basis for $l=0$. This calculates the HO wf's a bit differently than Fortran code above.
