Toda lattice field theories, discrete W algebras, Toda lattice hierarchies and quantum groups [PDF]

Physics Letters B, 1996
In analogy with the Liouville case we study the $sl_3$ Toda theory on the lattice and define the relevant quadratic algebra and out of it we recover the discrete $W_3$ algebra. We define an integrable system with respect to the latter and establish the relation with the Toda lattice hierarchy. We compute the the relevant continuum limits.

The chirally rotated Schrödinger functional: theoretical expectations and perturbative tests

Journal of High Energy Physics, 2016
The chirally rotated Schrödinger functional (χSF) with massless Wilson-type fermions provides an alternative lattice regularization of the Schrödinger functional (SF), with different lattice symmetries and a common continuum limit expected from ...

Isospin breaking corrections to meson masses and the hadronic vacuum polarization: a comparative study

Journal of High Energy Physics, 2017
We calculate the strong isospin breaking and QED corrections to meson masses and the hadronic vacuum polarization in an exploratory study on a 64 × 243 lattice with an inverse lattice spacing of a −1 = 1.78 GeV and an isospin symmetric pion mass of m π =

Induced QCD II: numerical results

Journal of High Energy Physics, 2019
We numerically explore an alternative discretization of continuum SU(N c ) Yang-Mills theory on a Euclidean spacetime lattice, originally introduced by Budzcies and Zirnbauer for gauge group U(N c ).

Quantum lattice gas algorithmic representation of gauge field theory [PDF]

Security + Defence, 2016
Presented is a quantum lattice gas algorithm to efficiently model a system of Dirac particles interacting through an intermediary gauge field. The algorithm uses a fixed qubit array to represent both the spacetime and the particles contained in the ...

Reconstructing parton distribution functions from Ioffe time data: from Bayesian methods to neural networks

Journal of High Energy Physics, 2019
The computation of the parton distribution functions (PDF) or distribution amplitudes (DA) of hadrons from first principles lattice QCD constitutes a central open problem in high energy nuclear physics.

A single-particle framework for unitary lattice gauge theory in discrete time

New Journal of Physics, 2022
We construct a real-time lattice-gauge-theory (LGT)-type action for a spin-1/2 matter field of a single particle on a $(1+1)$ -dimensional spacetime lattice.

Quantum Tetrahedra

, 2009
We discuss in details the role of Wigner 6j symbol as the basic building block unifying such different fields as state sum models for quantum geometry, topological quantum field theory, statistical lattice models and quantum computing.

Circuit-based digital adiabatic quantum simulation and pseudoquantum simulation as new approaches to lattice gauge theory

Journal of High Energy Physics, 2020
Gauge theory is the framework of the Standard Model of particle physics and is also important in condensed matter physics. As its major non-perturbative approach, lattice gauge theory is traditionally implemented using Monte Carlo simulation ...
