Description
A computationally efficient method for calculating the transport of neutrino flavor in simulations of supernovae or compact-object mergers is to use angular moments of the neutrino one-body reduced density matrix, i.e., 'quantum moments'. To implement this approach in a simulations we need to grapple with two fundamental issues: how to define a `closure' for the moments and how to adapt classical finite-volume approaches to transport so that we can advect the flavor coherence. In this talk I present our solutions to these two challenges and how results using our new methods compare with more exact multi-angle results.
