Efimov Physics and Connections to Nuclear Physics

Efimov Physics in Cold Atoms

Atoms with a large scattering length have universal low-energy properties that do not depend on the details of their structure or their interactions at short distances. In the 2-atom sector, the universal properties are familiar and depend only on the scattering length. In the 3-atom sector for identical bosons, the universal properties include the existence of a sequence of shallow triatomic m...

Efimov physics from a renormalization group perspective.

We discuss the physics of the Efimov effect from a renormalization group viewpoint using the concept of limit cycles. Furthermore, we discuss recent experiments providing evidence for the Efimov effect in ultracold gases and its relevance for nuclear systems.

Inflationary Models and Connections to Particle Physics †

The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that eternal inflation has real consequences in te...

Nuclear Physics

the first importance. Behnke has demonstrated that the "lean body mass," since it represents the active tissue of a person, is superior to reference standards hitherto proposed for the estimation of physiological functions such as the masses of various organs and tissues and the volumes of the different fluid compartments in the body. In the present article, which has been reprinted as a short ...
