An Alternative Lattice Field Theory Formulation Inspired by Lattice Supersymmetry-Summary of the Formulation- [PDF]
EPJ Web of Conferences, 2018 We propose a lattice field theory formulation which overcomes some fundamental diffculties in realizing exact supersymmetry on the lattice. The Leibniz rule for the difference operator can be recovered by defining a new product on the lattice, the star ...

Higgs-Yukawa Model in Chirally Invariant Lattice Field Theory [PDF]
Advances in High Energy Physics, 2013 Nonperturbative numerical lattice studies of the Higgs-Yukawa sector of the standard model with exact chiral symmetry are reviewed. In particular, we discuss bounds on the Higgs boson mass at the standard model top quark mass and in the presence of heavy

Exact Lattice Supersymmetry from Topological Field Theory [PDF]
, 2003 We discuss the connection between supersymmetric field theories and topological field theories and show how this connection may be used to construct local lattice field theories which maintain an exact supersymmetry.

Fractional Quantum Field Theory: From Lattice to Continuum
Advances in High Energy Physics, 2014 An approach to formulate fractional field theories on unbounded lattice space-time is suggested. A fractional-order analog of the lattice quantum field theories is considered.

Lattice Field Theory with the Sign Problem and the Maximum Entropy Method [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2007 Although numerical simulation in lattice field theory is one of the most effective tools to study non-perturbative properties of field theories, it faces serious obstacles coming from the sign problem in some theories such as finite density QCD and ...

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

Control variates for lattice field theory [PDF]
Physical Review D, 2023 In most lattice field theories, correlators are plagued by a signal-to-noise problem of exponential difficulty in the time separation. We propose a method for improving the signal-to-noise ratio, in which control variates are systematically constructed ...

Quantum mean estimation for lattice field theory [PDF]
Quantum mean estimation for lattice field theory, 2023 We demonstrate the quantum mean estimation algorithm on Euclidean lattice field theories. This shows a quadratic advantage over Monte Carlo methods which persists even in presence of a sign problem, and is insensitive to critical slowing down.

Stochastic normalizing flows for lattice field theory [PDF]
Proceedings of The 39th International Symposium on Lattice Field Theory — PoS(LATTICE2022), 2022 Stochastic normalizing flows are a class of deep generative models that combine normalizing flows with Monte Carlo updates and can be used in lattice field theory to sample from Boltzmann distributions.

A chaotic lattice field theory in one dimension [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 Motivated by Gutzwiller’s semiclassical quantization, in which unstable periodic orbits of low-dimensional deterministic dynamics serve as a WKB ‘skeleton’ for chaotic quantum mechanics, we construct the corresponding deterministic skeleton for infinite ...
