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

Advances in machine-learning-based sampling motivated by lattice quantum chromodynamics [PDF]
Nature Reviews Physics, 2023 Machine-learning-based sampling strategies have been recently developed for lattice quantum chromodynamics applications. These methods are in their early stages, but have the potential to enable currently intractable first-principles calculations in ...

Entanglement entropy and quantum field theory [PDF]
, 2004 We carry out a systematic study of entanglement entropy in relativistic quantum field theory. This is defined as the von Neumann entropy SA = −Tr ρAlogρA corresponding to the reduced density matrix ρA of a subsystem A.

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

Tensor renormalization group study of two-dimensional U(1) lattice gauge theory with a θ term
Journal of High Energy Physics, 2020 We make an analysis of the two-dimensional U(1) lattice gauge theory with a θ term by using the tensor renormalization group. Our numerical result for the free energy shows good consistency with the exact one at finite coupling constant.

Critical 1- and 2-point spin correlations for the O(2) model in 3d bounded domains
Journal of High Energy Physics, 2021 We study the critical properties of the 3d O(2) universality class in bounded domains through Monte Carlo simulations of the clock model. We use an improved version of the latter, chosen to minimize finite-size corrections at criticality, with 8 ...

Holographic quantum states [PDF]
, 2010 We show how continuous matrix product states of quantum field theories can be described in terms of the dissipative non-equilibrium dynamics of a lower-dimensional auxiliary boundary field theory.

The flavor dependence of m ϱ /f π
Journal of High Energy Physics, 2019 We calculate the m ϱ /f π 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. Keeping all systematic effects under full control we find no statistically significant N f

CONNECTIONS of the LIOUVILLE MODEL and XXZ SPIN CHAIN [PDF]
, 1995 The quantum theory of the Liouville model with imaginary field is considered using the quantum inverse scattering method. An integrable structure with nontrivial spectral parameter dependence is developed for lattice Liouville theory by scaling the $L ...
