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, On the Use of the Discrete Variable Representation Basis in Nuclear Physics, Phys. Rev. C 87,  051301(R)  (2013)

• The LISE package aimed at simulating time-dependent 3D nuclear systems, the numerical implementation of the (TD)SLDA description and code download are available.

• The W-SLDA Toolkit aimed at simulating time-dependent 3D strongly interacting cold fermionic atom systems, the numerical implementation of the (TD)SLDA description and code are available here.

                                           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.)
