Hans-Werner Hammer (Bonn):

Universal EFT for strongly interacting quantum systems

Abstract:

Effective field theories provide a powerful framework to exploit a separation of scales in physical systems. I will discuss the application of this method to resonant few-body systems with large scattering length. Such systems show universal behavior and can display the Efimov effect and log-periodic scaling. Finally, I will discuss some applications ranging from nuclear and particle physics to the physics of ultracold atoms.
