Neutrino–matter interactions play an important role in core-collapse supernova (CCSN)
explosions, as they contribute to both lepton number and/or four-momentum exchange …

We apply the collision-based hybrid method introduced by Hauck and McClarren [1] to the
Boltzmann equation with the BGK operator and a hyperbolic scaling. An implicit treatment of …

We provide rigorous theoretical bounds for Anderson acceleration (AA) that allow for
approximate calculations when applied to solve linear problems. We show that, when the …

A key property of the linear Boltzmann semiconductor model is that as the collision
frequency tends to infinity, the phase space density converges to an isotropic function, called …

We present and analyze a new iterative solver for implicit discretizations of a simplified
Boltzmann--Poisson system. The algorithm builds on recent work that incorporated a …

In this paper, we consider the high order method for solving the linear transport equations
under diffusive scaling and with random inputs. To tackle the randomness in the problem …
