Nuclear energy density optimization [PDF]

open access: yesPhysical Review C, 2010
We carry out state-of-the-art optimization of a nuclear energy density of Skyrme type in the framework of the Hartree-Fock-Bogoliubov (HFB) theory. The particle-hole and particle-particle channels are optimized simultaneously, and the experimental data set includes both spherical and deformed nuclei.

Optimal Renewable-Energy Subsidies [PDF]

open access: yesSSRN Electronic Journal, 2014
We derive optimal subsidization of renewable energies in electricity markets. The analysis takes into account that capacity investment must be chosen under uncertainty about demand conditions and capacity availability, and that capacity as well as electricity generation may be sources of externalities.
