Abstract:
The Higgs mechanism and the Meissner effect in superconductors are twins, and provide an inspirational connector between field theories in condensed matter physics and particle physics. In particle physics the observation of the Higgs particle is a triumph that substantiates the standard model. In condensed matter, the corresponding particle has less fundamental significance. But condensed matter physics has the advantage of easier experiments, and more “universes” than HEP. I will discuss Higgs-like (“amplitude”) modes in condensed matter systems, their observation, and their complexities ; in many cases in condensed matter, Higgs modes have hair, are embedded in continua, have strong decay channels, and are difficult to observe.
