Generative Diffusion Models for Lattice Field Theory

arXiv.org, 2023
This study delves into the connection between machine learning and lattice field theory by linking generative diffusion models (DMs) with stochastic quantization, from a stochastic differential equation perspective. We show that DMs can be conceptualized

Quantum group symmetries in two-dimensional lattice quantum field theory

Nuclear Physics B, 1991
Abstract We present a general theory of non-local conserved currents in two-dimensional quantum field theory in the lattice approximation. They reflect quantum group symmetries. Various examples are studied.

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 ...

Sign Problems in Quantum Field Theory: Classical and Quantum Approaches

, 2020
Monte Carlo calculations in the framework of lattice field theory provide non-perturbative access to the equilibrium physics of quantum fields. When applied to certain fermionic systems, or to the calculation of out-of-equilibrium physics, these methods ...

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 ...

MCMC and Quantum Field Theories on a Lattice

2020
We can consider relativistic quantum field theory as the quantum mechanics of fields defined on a spacetime. A field has infinite number of degrees of freedom since it can take a value at every point in spacetime.

A quantum field theory of melting and lattice dynamics

Physica A: Statistical Mechanics and its Applications, 1986
Abstract The melting and the lattice dynamics are investigated from the view-point of a quantum field theory at finite temperature (thermo field theory). Our theory starts with ion cores and valence electrons interacting with each other as the first principle.
