Achieving the quantum field theory limit in far-from-equilibrium quantum link models [PDF]

open access: yesQuantum, 2022
Realizations of gauge theories in setups of quantum synthetic matter open up the possibility of probing salient exotic phenomena in condensed matter and high-energy physics, along with potential applications in quantum information and science ...

Isospin-1/2 Dπ scattering and the lightest D 0 ∗ $$ {D}_0^{\ast } $$ resonance from lattice QCD

open access: yesJournal of High Energy Physics, 2021
Isospin-1/2 Dπ scattering amplitudes are computed using lattice QCD, working in a single volume of approximately (3.6 fm)3 and with a light quark mass corresponding to m π ≈ 239 MeV.

Lattice field theory results for hybrid static potentials at short quark-antiquark separations and their parametrization [PDF]

open access: yes, 2022
We present SU(3) lattice Yang-Mills data for hybrid static potentials from five ensembles with different small lattice spacings and the corresponding parametrizations for quark-antiquark separations $0.08\,\text{fm} \le r \le 1.12\,\text{fm}$.

Relativistic N-particle energy shift in finite volume

open access: yesJournal of High Energy Physics, 2021
We present a general method for deriving the energy shift of an interacting system of N spinless particles in a finite volume. To this end, we use the nonrelativistic effective field theory (NREFT), and match the pertinent low-energy constants to the ...

The continuum and leading twist limits of parton distribution functions in lattice QCD

open access: yesJournal of High Energy Physics, 2021
In this study, we present continuum limit results for the unpolarized parton distribution function of the nucleon computed in lattice QCD. This study is the first continuum limit using the pseudo-PDF approach with Short Distance Factorization for ...

Quantum field theory on a growing lattice [PDF]

open access: yesJournal of High Energy Physics, 2004
We construct the classical and canonically quantized theories of a massless scalar field on a background lattice in which the number of points--and hence the number of modes--may grow in time. To obtain a well-defined theory certain restrictions must be imposed on the lattice.

Learning lattice quantum field theories with equivariant continuous flows

open access: yesSciPost Physics, 2023
We propose a novel machine learning method for sampling from the high-dimensional probability distributions of Lattice Field Theories, which is based on a single neural ODE layer and incorporates the full symmetries of the problem. We test our model on the \phi^4

Taking Particle Physics Seriously: a Critique of the Algebraic Approach to Quantum Field Theory [PDF]

open access: yes, 2011
I argue against the currently-prevalent view in philosophy of physics that algebraic quantum field theory (AQFT) is the correct framework for philosophy of quantum field theory and that "conventional" quantum field theory (CQFT), of the sort used in ...

Moments of Ioffe time parton distribution functions from non-local matrix elements

open access: yesJournal of High Energy Physics, 2018
We examine the relation of moments of parton distribution functions to matrix elements of non-local operators computed in lattice quantum chromodynamics.
