Following COVID-19 advice I will be in the office only occasionally and teach remotely using zoom, until further notice.

**Numerical
Programs
** Here I shall add from time to time
various relatively small numerical programs I have written
and which others might find useful. Please do not
count on any help of any kind on my part, apart from the
comments in the write-up, you will have to figure out
everything if you want to use it, how to use it and all
the rest. However, if you use it, please let me know about
that and include the corresponding acknowledgment in
the relevant documents.

- Here is an implementation of SLDA using the Bessel-DVR and the Broyden algorithm for updating the fields and the chemical potentials, used for determining the properties of a trapped two-component Fermi gas with an arbitrary total pseudo-spin. The slda_broyden__bessel program was written in matlab. Here is a python code, written by M.M. Forbes, solving the same problem by varying the effective mass. For theory see: A. Bulgac, Local Density Functional Theory for Superfluid Fermionic Systems: The Unitary Gas, Phys. Rev. A 76 040502(R) (2007)

- Four
matlab codes implementing the Lanczos algorithm and the
imaginary time evolution for determining the ground state wave
functions (and excited states as well in case of
Lanczos) of a triton and alpha particles with central forces
only using Jacobi coordinates and which can be run on a
laptop. For theory see: A. Bulgac and M.M. Forbes,

Gribov (BH) **

**(That was my graduate school. I was the speaker at one of
those seminars,

which started in the late morning, no lunch break, and ended in
late afternoon.

Only after my work was dissected to the bone, and BH was one of
the main debaters,

I was allowed to officially defend my thesis.)
