Title Condensed matter physics for dark matter detection
Abstract Recently many ideas have been proposed for light dark matter detection using low energy excitations in solid state, such as phonons, magnons and electrons. I will review some basics of condensed matter physics: the Bloch state of the electron in solid state, collective excitations and their dispersion. As an example I discuss a magnon, which is a quantized spin-wave excitation, as a target to detect axion/hidden-photon dark matter with meV range.
