The nature of the dark matter remains one of the most compelling outstanding questions in physics. Theoretical and experimental focus has been directed in the last several decades on New Physics at the weak scale, where the dark matter dynamics are parasitic on the ordinary standard model forces. We are now looking beyond the weak scale dark matter paradigm towards theories of dark matter with their own dark sector forces. These theories lead to many new signatures both in the cosmos and in the laboratory, and ideas to search for these hidden sectors abound. I describe some of these new ideas, focusing on quantum materials and quantum sensors.
