A Gentle Introduction to Lattice Field Theory

Entropy
The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular ...

Fractional Quantum Field Theory: From Lattice to Continuum [PDF]

Advances in High Energy Physics, 2014
An approach to formulate fractional field theories on unbounded lattice space-time is suggested. A fractional-order analog of the lattice quantum field theories is considered.

Relativistic N-particle energy shift in finite volume

Journal 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 ...

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

, 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 $0.08\,\text{fm} \le r \le 1.12\,\text{fm}$.

Implementing the three-particle quantization condition for π + π + K + and related systems

Journal of High Energy Physics, 2022
Recently, the formalism needed to relate the finite-volume spectrum of systems of nondegenerate spinless particles has been derived. In this work we discuss a range of issues that arise when implementing this formalism in practice, provide further ...

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

Quantum, 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 ...

More on the flavor dependence of m ϱ /f π

Journal of High Energy Physics, 2021
In previous work, [ arXiv:1905.01909 ], we have calculated the m ϱ /fπ ratio in the chiral and continuum limit for SU(3) gauge theory coupled to N f = 2, 3, 4, 5, 6 fermions in the fundamental representation.

Review on Quantum Computing for Lattice Field Theory [PDF]

, 2023
In these proceedings, we review recent advances in applying quantum computing to lattice field theory. Quantum computing offers the prospect to simulate lattice field theories in parameter regimes that are largely inaccessible with the conventional Monte

Nucleon momentum fraction, helicity and transversity from 2+1-flavor lattice QCD

Journal of High Energy Physics, 2021
A detailed analysis of the systematic uncertainties in the calculation of the isovector momentum fraction, 〈x〉 u − d , helicity moment, 〈x〉Δu − Δd , and the transversity moment, 〈x〉 δu − δd , of the nucleon is presented using high-statistics data on ...

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

Journal 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.
