Quantum Tetrahedral Mean Field Theory of the Magnetic Susceptibility for the Pyrochlore Lattice [PDF]

Physical Review Letters, 2000
A quantum mean field theory of the pyrochlore lattice is presented. The starting point is not the individual magnetic ions, as in the usual Curie-Weiss mean field theory, but a set of interacting corner sharing tetrahedra. We check the consistency of the model against magnetic susceptibility data, and find a good agreement between the theoretical ...

Lattice Integrable Models of Quantum Field Theory [PDF]

, 1993
The quantum inverse scattering method allows one to put quantum field theory models on a lattice in a way which preservesthe dynamicalstructure.The trace identitiesare discussedfor thesemodels.

Quantum Cellular Automata from Lattice Field Theories

, 2003
We apply the methods of lattice field theories to the quantization of cellular automata. We discuss the quantization of five main categories of cellular automata: bosonic, fermionic, supersymmetric, spin and quantum dot using path integral and operator formalisms of lattice field theories.

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.

Disordered Lattice Glass $\phi^{4}$ Quantum Field Theory [PDF]

We study numerically the three-dimensional $ϕ^{4}$ spin glass, a prototypical disordered and discretized Euclidean field theory that manifests inhomogeneities in space and time but considers a homogeneous squared mass and lambda terms. The $ϕ^{4}$ lattice glass field theory is a conceptual generalization of spin glasses to continuous degrees of freedom

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.
