The scenario of a mobile impurity immersed in a Fermi gas appears in a wide variety of systems ranging from neutron stars to cold atomic gases to the absorption spectra in doped semiconductors. In this case, the impurity attractively interacts with the surrounding fermions and becomes “dressed” by excitations of the Fermi gas to form a quasiparticle, a particle-like object with a different mass from the bare impurity. In this talk, I will discuss how cold atoms can provide fundamental insight into the nature of these quasiparticles, particularly how they can break down in a manner not previously explored in Fermi systems.
A collaboration between FLEET and our partner, Joint Quantum Institute at the University of Maryland, this United States – Australia Transpacific Colloquium will present novel developments in condensed matter and cold atomic physics. It aims to enrich connections between the physics communities.
