Structure-dependent electromagnetic finite-volume effects through order
Matteo Di Carlo, Maxwell T. Hansen, Nils Hermansson-Truedsson +1
We consider electromagnetic finite-volume effects through order in different formulations of QED, where is the periodicity of the spatial volume. An inherent problem at…
Exploiting stochastic locality in lattice QCD: hadronic observables and their uncertainties
Mattia Bruno, Marco Cè, Anthony Francis +4
Because of the mass gap, lattice QCD simulations exhibit stochastic locality: distant regions of the lattice fluctuate independently. There is a long history of exploiting this to…
Higher partial wave contamination in finite-volume 1-to-2 transitions
Toby Peterken, Maxwell T. Hansen
In their seminal work, Lellouch and Lüscher derived a conversion factor relating a finite-volume matrix element, calculable using numerical lattice QCD, with the infinite-volume de…
Three relativistic neutrons in a finite volume
Zachary T. Draper, Maxwell T. Hansen, Fernando Romero-López +1
We generalize the relativistic field-theoretic (RFT) three-particle finite-volume formalism to systems of three identical, massive, spin- fermions, such as three neutrons. Thi…
Hadronic observables from master-field simulations
Marco Cè, Mattia Bruno, John Bulava +5
Substantial progress has been made recently in the generation of master-field ensembles. This has to be paired with efficient techniques to compute observables on gauge field confi…
The Lüscher scattering formalism on the -channel cut
André Baião Raposo, Maxwell T. Hansen
The Lüscher scattering formalism, the standard approach for relating the discrete finite-volume energy spectrum to two-to-two scattering amplitudes, fails when analytically continu…
