Colloquium – Wei Xue (UF Physics)

Date March 24 @ 3:00 pm - 4:00 pm

New ideas of dark matter theories and searches

The nature of dark matter is a central question in fundamental physics. To discover dark matter, we need to build new dark matter frameworks and new search strategies. I will present my recent works on dark matter experiment, theory and dark matter evolution in the early universe. First, I will introduce a new development in an effective theory of helium superfluid. The theory development is the first step of a long project to build a dark matter direct detection detector using helium superfluid to search for MeV-GeV mass dark matter. Second, I will introduce a new paradigm, where dark matter is made up of a novel form of matter, called “gapped continuum,” rather than an ordinary particle. Third, I will discuss the momentum spectrum of axion dark matter during the a phase transition in the early universe.
