Multigrid Preconditioning for the Overlap Operator in Lattice QCD
James Brannick, Andreas Frommer, Karsten Kahl +3
The overlap operator is a lattice discretization of the Dirac operator of quantum chromodynamics, the fundamental physical theory of the strong interaction between the quarks. As o…
Microphysics of Neutron Star Outer Envelopes in the Periodized, Magnetic Thomas-Fermi Model
Tyler A. Engstrom, Vincent H. Crespi, Benjamin J. Owen +2
Static and dynamic properties of low density outer envelopes of neutron stars are calculated within the nonlinear magnetic Thomas-Fermi model, assuming degenerate electrons. A nove…
Bootstrap Algebraic Multigrid: status report, open problems, and outlook
Achi Brandt, James Brannick, Karsten Kahl +1
This paper provides an overview of the main ideas driving the bootstrap algebraic multigrid methodology, including compatible relaxation and algebraic distances for defining effect…
Diffuse Interface Methods for Multiple Phase Materials: An Energetic Variational Approach
J. Brannick, C. Liu, T. Qian +1
In this paper, we introduce a diffuse interface model for describing the dynamics of mixtures involving multiple (two or more) phases. The coupled hydrodynamical system is derived…
An Adaptively Constructed Algebraic Multigrid Preconditioner for Irreducible Markov Chains
James Brannick, Karsten Kahl, Sonja Sokolovic
The computation of stationary distributions of Markov chains is an important task in the simulation of stochastic models. The linear systems arising in such applications involve no…
