Fractional Quantum Field Theory: From Lattice to Continuum [PDF]

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.

Quantum field theory on a growing lattice [PDF]

Journal of High Energy Physics, 2004
We construct the classical and canonically quantized theories of a massless scalar field on a background lattice in which the number of points--and hence the number of modes--may grow in time.

Quantum Finite Elements for Lattice Field Theory [PDF]

Proceedings of The 33rd International Symposium on Lattice Field Theory — PoS(LATTICE 2015), 2016
Viable non-perturbative methods for lattice quantum field theories on curved manifolds are difficult. By adapting features from the traditional finite element methods (FEM) and Regge Calculus, a new simplicial lattice Quantum Finite Element (QFE ...

Quantum simulation of quantum field theories as quantum chemistry

Journal of High Energy Physics, 2020
Conformal truncation is a powerful numerical method for solving generic strongly-coupled quantum field theories based on purely field-theoretic technics without introducing lattice regularization.

A Gentle Introduction to Lattice Field Theory [PDF]

Entropy
The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular ...

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 ...
