Signatures from Non-classical Features of Axion Dark Matter in Cavity Haloscopes

Abstract

I present in this article how non-classical features in the local axion dark matter state may imprint on cavity haloscopes. Example signatures from squeezed and pair-entangled DM states are presented and their potential for sensitivity enhancements of experimental searches attuned to these signatures compared to traditional classical field signatures are discussed.
