Few-body Perspectives on Many Interacting Fermions
Monday, November 27, 2006
The problem of many interacting fermions touches many areas of physics, from superconductivity to dense nuclear matter. One of the richest fermionic systems is a dilute gas of fermionic alkali atoms in the regime where the atom-atom interactions grow very strong. This is the so-called BCS-BEC crossover problem. This colloquium will give an overview of that problem, including a discussion of some insights that can be gleaned by studying the strongly-coupled 2-, 3-, and 4-body subsystems.
