Radial lattice quantization of 3D ϕ4 field theory [PDF]

open access: yesPhysical Review D, 2020
The quantum extension of classical finite elements, referred to as quantum finite elements ({\bf QFE})~\cite{Brower:2018szu,Brower:2016vsl}, is applied to the radial quantization of 3d $\phi^4$ theory on a simplicial lattice for the $\mathbb R \times ...

Consistency between Lüscher’s finite volume method and HAL QCD method for two-baryon systems in lattice QCD

open access: yesJournal of High Energy Physics, 2019
There exist two methods to study two-baryon systems in lattice QCD: the direct method which extracts eigenenergies from the plateaux of the temporal correlation function and the HAL QCD method which extracts observables from the non-local potential ...

Thermal QCD in a non-uniform magnetic background

open access: yesJournal of High Energy Physics, 2023
Off-central heavy-ion collisions are known to feature magnetic fields with magnitudes and characteristic gradients corresponding to the scale of the strong interactions.

Renormalization group theory of nematic ordering in d-wave superconductors [PDF]

open access: yes, 2008
We examine the quantum theory of the spontaneous breaking of lattice rotation symmetry in d-wave superconductors on the square lattice. This is described by a field theory of an Ising nematic order parameter coupled to the gapless fermionic ...

QUASI-TOPOLOGICAL QUANTUM FIELD THEORIES AND ℤ2 LATTICE GAUGE THEORIES [PDF]

open access: yesInternational Journal of Modern Physics A, 2012
We consider a two-parameter family of ℤ2 gauge theories on a lattice discretization [Formula: see text] of a three-manifold [Formula: see text] and its relation to topological field theories. Familiar models such as the spin-gauge model are curves on a parameter space Γ.

Parton distribution functions from Ioffe time pseudo-distributions

open access: yesJournal of High Energy Physics, 2019
In this paper, we present a detailed study of the unpolarized nucleon parton distribution function (PDF) employing the approach of parton pseudo-distribution func- tions. We perform a systematic analysis using three lattice ensembles at two volumes, with

Lattice Wess-Zumino-Witten Model and Quantum Groups [PDF]

open access: yes, 1992
Quantum groups play a role of symmetries of integrable theories in two dimensions. They may be detected on the classical level as Poisson-Lie symmetries of the corresponding phase spaces.

Simulating quantum field theory with a quantum computer [PDF]

open access: yesProceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018), 2018
Forthcoming exascale digital computers will further advance our knowledge of quantum chromodynamics, but formidable challenges will remain. In particular, Euclidean Monte Carlo methods are not well suited for studying real-time evolution in hadronic ...

Tensor polarizability of the vector mesons from SU(3) lattice gauge theory

open access: yesJournal of High Energy Physics, 2018
The magnetic dipole polarizabilities of the vector ρ 0 and ρ ± mesons in SU(3) pure gauge theory are calculated in the article. Based on this the authors explore the contribution of the dipole magnetic polarizabilities to the tensor polarization of the ...

N $$ \mathcal{N} $$ = 1 Super-Yang-Mills theory on the lattice with twisted mass fermions

open access: yesJournal of High Energy Physics, 2021
Super-Yang-Mills theory (SYM) is a central building block for supersymmetric extensions of the Standard Model of particle physics. Whereas the weakly coupled subsector of the latter can be treated within a perturbative setting, the strongly coupled ...
