Entropy, area, and the choice of regulator during gravitational collapse
Jana N. Guenther, Christian Hoelbling, Sophie Mutzel +1
We present a real time formalism to numerically describe the gravitational collapse of a scalar quantum field in the spherically symmetric case. We employ a Pauli-Villars regulator…
Certified spectral functions from lattice Monte Carlo data
Sophie Mutzel, Antoine Tilloy
The Monte Carlo method, applied to lattice quantum field theory, gives access to Euclidean correlation functions with well-understood error bars. Recovering the observables one car…
BMW/DMZ calculation of the hadronic vacuum polarisation for the muon magnetic moment
Finn M. Stokes, Alessandro Cotellucci, Michel Davier +11
For twenty years, a persistent discrepancy between experimental measurements and theoretical calculations of the muon anomalous magnetic moment have provided tantalising hints of n…
Extracting quantum field theory dynamics from an approximate ground state
Sophie Mutzel, Antoine Tilloy
We develop a linear-programming method to extract dynamical information from static ground-state correlators in quantum field theory. We recast the Källén-Lehmann inversion as a co…
Hadronic contribution to the running of the electromagnetic coupling constant from lattice QCD: challenges at short distances
Sophie Mutzel
The electromagnetic coupling constant, , is one of the fundamental parameters of the Standard Model (SM). Its value at the Z boson mass, , is of particular interest as i…
Axion-like particles as mediators for dark matter: beyond freeze-out
A. Bharucha, F. Brümmer, N. Desai +1
We consider an axion-like particle (ALP) coupled to Standard Model (SM) fermions as a mediator between the SM and a fermionic dark matter (DM) particle. We explore the case where t…
An open and parallel multiresolution framework using block-based adaptive grids
Mario Sroka, Thomas Engels, Philipp Krah +3
A numerical approach for solving evolutionary partial differential equations in two and three space dimensions on block-based adaptive grids is presented. The numerical discretizat…
