Parallel NFS Nuclear Forces and Structure, NN Correlations, and Medium Effects

Speaker

Prof. Calvin Johnson (San Diego State University)

Description

Today there are a plethora of many-body techniques for calculating nuclear wave functions and matrix elements. I will review the status of that reliable workhorse, the interacting shell model, a.k.a. configuration-interaction methods, a.k.a. Hamiltonian diagonalization, and survey its advantages and disadvantages. With modern supercomputers one can tackle dimensions up to about 20 billion! I will discuss prospects for going even further, and what one hopes to learn.
