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.
