Bogner, H. Toggle Search and Navigation Menu. Shaw Lane, Room hergert nscl. Calculations are performed on systems ranging from mid-size computing clusters to massively parallel supercomputers. Calculations are necessarily parallelized, and run on mid-size computing clusters or massively parallel systems, depending on the specific problem. Ab initio i.

This is mainly due to the complicated nature. The focus of my work is on applications of renormalization group methods, in particular the Similarity Renormalization Group (SRG), in the field of nuclear.
Ground-state energies of oxygen isotopes from chiral two- plus three-nucleon interactions, calculated with a variety of ab initio many-body methods.
He describes his research interests and projects as follows. Thus, one challenges we face is to ensure good use of the continuously changing architectures of high-performance computers.

While deceptively easy to write down, QCD is hard to solve. The confrontation of our calculations with new experimental data will also allow us to diagnose and resolve issues of the chiral interactions, in collaboration with EFT practitioners. An important feature of this approach is that we control the theoretical uncertainties of each ingredient; i.

The interplay of the complicated nuclear interactions with quantum-mechanical many-body effects gives rise to a rich variety of nuclear phenomena. This will increase the number of accessible isotopes more than tenfold.
I am now developing tools to calculate the properties of entire chains of so-called open-shell nuclei.

While deceptively easy to write down, QCD is very hard to solve. By developing efficient new methods, my colleagues and I have extended the range of accessible nuclei from light isotopes like carbon atomic number 6 to tin atomic number
For instance, one of the biggest obstacles we face in ab initio calculations are the massive memory requirements of three-nucleon interactions, which cannot be met by even the largest supercomputers.
