A Quantum Description of Wave Dark Matter
Nicholas Rodd, LBNL,

In this talk I will outline a fundamentally quantum description of bosonic dark matter from which the conventional classical-wave picture emerges when the mass is far below 10 eV. Exploiting fundamental results from quantum optics I will argue that the density matrix for dark matter is explicitly mixed and describe how to precisely define and understand the coherent properties of the wave. The formalism further provides a continuous description of DM through the wave-particle transition, and using this I show how density fluctuations over various physical scales evolve between the two limits, with a unique behavior for DM emerging near the boundary of the wave and particle descriptions.

The talk is in 469 Lauritsen.
