Location:  Auditorium          

Speaker:   Dick Furnstahl (Ohio State University)

Title:     Atomic Nuclei at Low Resolution

Abstract: 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 potentials and wave-function correlations.  I will illustrate the machinery and consequences of lowering the resolution and outline the benefits for major nuclear theory initiatives such as a project to develop a Universal Nuclear Energy Density Functional (UNEDF).

Stimulants available 15 minutes before the talk.
