Atomic Nuclei at Low Resolution
R. Furnstahl (Ohio State)
For digital televisions and cameras, higher resolution is considered better. Progress in particle physics requires higher resolution (shorter wavelengths) using higher energy accelerators. But for many-body problems, such as the microscopic description of nuclei, lowering the resolution can be a big advantage. Evolving Hamiltonians to low resolution involves only basic principles of quantum mechanics, but with less familiar features such as nonlocality and many-body forces, which can run counter to intuition about wave functions and potentials. I will illustrate the machinery and consequences of lowering the resolution and outline the benefits for major nuclear structure initiatives such as a project to develop a Universal Nuclear Energy Density Functional (UNEDF).
