Lattice fractional quantum field theory: Exact differences approach

Modern Physics Letters A, 2020
An approach, which is based on exact fractional differences, is used to formulate a lattice fractional field theories on unbounded lattice spacetime. An exact discretization of differential and integral operators of integer and non-integer orders is suggested.

Quantum Field Theory (QFT) on the Lattice

2016
In 1964, Gell-Mann [1] and Zweig [2] proposed that hadrons, the particles which experience strong interactions, are made of quarks. Quarks are confined within hadrons and never seen in isolation. Electron-nucleon scattering experiments at large momentum transfer could be explained by assuming the nucleon is made of almost-free point-like constituents ...

Lattice Boltzmann method for quantum field theory

Journal of Physics A: Mathematical and Theoretical, 2007
It is shown that a (1 + 1)-dimensional lattice Boltzmann discretization of the Klein–Gordon and Dirac equations complies with equal-time-commutation-relations. As a result, the lattice Boltzmann discretization leads to a consistent lattice formulation of the quantum field theory in 1 + 1 dimensions.

Scattering and Bound States in Euclidean Lattice Quantum Field Theories

Annales Henri Poincaré, 2001
The problem of asymptotic completeness (AC) is the question whether all pure states can be interpreted in terms of scattering states of particles. The authors study here the two-body AC in massive Euclidean lattice quantum field theories. Schwinger \(n\)-point functions \(S_n(x_1,\dots, x_n)\), \(x_i\in \mathbb{Z}^{d+1}\) with \(d\geq 1\), and Bethe ...

Lower bounds for quantum Hamiltonians in lattice field theories

Physical Review D, 1978
A method for approximately including quantum effects on the solution to lattice field theories is presented. The formalism is an extension of the semiquantum approximation of Sachrajda, Weldon, and Blankenbecler to obtain lower bounds for quantum Hamiltonians. This approach yields classical-like equations in which the effects of quantum fluctuations is
