The nature of dark matter is one of the most enduring cosmological mysteries. Dark matter candidates that behave as waves, rather than particles, connect the prolific areas of particle physics, astrophysics, condensed matter physics and quantum information. In this colloquium I will discuss a variety of novel methods exploiting the medium properties of materials to search for wavelike dark matter, with a particular focus on the axion. By creating tunable resonances in material properties (quasiparticles) we can search for wavelike dark matter in higher frequencies than accessible by traditional methods. In addition to this I show how the coupling of axions to fermion spins generates currents that induce detectable electromagnetic radiation. Combining these approaches opens up the 10^-5 eV to 10 eV mass parameter space to powerful dark matter searches.
