Sampling SU(N) gauge theory on a 2D lattice from independent plaquettes via holonomies and corner reweighting
Javad Komijani
In the Wilson formulation of lattice gauge theory, the fundamental degrees of freedom are group-valued link variables, while the action is a sum over the trace of the plaquettes, t…
Noise scheduling and linear dynamics in diffusion models on Lie groups
Javad Komijani
We investigate the role of the noise schedule in diffusion processes on Lie groups, with particular emphasis on applications to lattice gauge theory. We show that a specific noise…
Diffusion model for SU(N) gauge theories
Javad Komijani, Marina K. Marinkovic, Lara Turgut
Implicit score matching provides a computationally efficient approach for training diffusion models and generating high-quality samples from complex distributions. In this work, we…
Group-Equivariant Diffusion Models for Lattice Field Theory
Octavio Vega, Javad Komijani, Aida El-Khadra +1
Near the critical point, Markov Chain Monte Carlo (MCMC) simulations of lattice quantum field theories (LQFT) become increasingly inefficient due to critical slowing down. In this…
Normalizing flows for SU() gauge theories employing singular value decomposition
Javad Komijani, Marina K. Marinkovic
We present a progress report on the use of normalizing flows for generating gauge field configurations in pure SU(N) gauge theories. We discuss how the singular value decomposition…
A discussion on leading renormalon in the pole mass
Javad Komijani
Perturbative series of some quantities in quantum field theories, such as the pole mass of a quark, suffer from a kind of divergence called renormalon divergence. In this paper, th…
Nonlinear eigenvalue problems
Carl M. Bender, Andreas Fring, Javad Komijani
This paper presents a detailed asymptotic study of the nonlinear differential equation y'(x)=\cos[πxy(x)] subject to the initial condition y(0)=a. Although the differential equatio…
