Learning lattice quantum field theories with equivariant continuous flows [PDF]
SciPost Physics, 2023 We propose a novel machine learning method for sampling from the high-dimensional probability distributions of Lattice Field Theories, which is based on a single neural ODE layer and incorporates the full symmetries of the problem. We test our model on the \phi^4

Review on Quantum Computing for Lattice Field Theory [PDF]
Proceedings of The 39th International Symposium on Lattice Field Theory — PoS(LATTICE2022), 2023 In these proceedings, we review recent advances in applying quantum computing to lattice field theory. Quantum computing offers the prospect to simulate lattice field theories in parameter regimes that are largely inaccessible with the conventional Monte Carlo approach, such as the sign-problem afflicted regimes of finite baryon density, topological ...

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.

Strategies for quantum-optimized construction of interpolating operators in classical simulations of lattice quantum field theories [PDF]
Physical Review D, 2022 It has recently been argued that noisy intermediate-scale quantum computers may be used to optimize interpolating operator constructions for lattice quantum field theory (LQFT) calculations on classical computers.

Diffusion models as stochastic quantization in lattice field theory [PDF]
Journal of High Energy Physics, 2023 In this work, we establish a direct connection between generative diffusion models (DMs) and stochastic quantization (SQ). The DM is realized by approximating the reversal of a stochastic process dictated by the Langevin equation, generating samples from

Krylov complexity in quantum field theory, and beyond [PDF]
Journal of High Energy Physics, 2022 We study Krylov complexity in various models of quantum field theory: free massive bosons and fermions on flat space and on spheres, holographic models, and lattice models with a UV-cutoff.

Entanglement Hamiltonians: From Field Theory to Lattice Models and Experiments [PDF]
Annals of Physics, 2022 Results about entanglement (or modular) Hamiltonians of quantum many‐body systems in field theory and statistical mechanics models, and recent applications in the context of quantum information and quantum simulation, are reviewed.
