The Amplitude Mode in Condensed Matter : Higgs Hunting on a Budget 

Daniel Arovas (University of California, San Diego )

The amplitude mode is a ubiquitous phenomenon in systems with broken continuous symmetry and effective relativistic dynamics, and has been observed in magnets, charge density waves, cold atom systems, and superconductors.  It is a simple analog of the Higgs boson of particle physics.  I will discuss the properties of the amplitude mode and its somewhat surprising visibility in two-dimensional systems, recently confirmed in cold atom experiments.  The behavior in the vicinity of a quantum critical point will be stressed, comparing theoretical, numerical, and experimental results.

Cette conférence s'adresse à tous, y compris les professeurs, les chercheurs et les étudiants des trois cycles.
