Weakly-interacting massive particle (WIMP) dark matter has been the leading paradigm for decades, but experimental searches for non-gravitational signatures of WIMPs have not found any positive evidence yet, which motivates us to think about new frameworks for dark matter and new strategies to search for it. My talk consists of two directions going beyond WIMP. First, I will introduce a new development in an effective field theory of helium superfluid. This is the first step of a long project to build a dark matter direct detection detector using superfluid 4He to search for sub-GeV dark matter. The other part of my talk will introduce a new paradigm, where DM is made up of a novel form of matter, called “gapped continuum”, rather than an ordinary particle.
