fcc lattice, checkerboards, fractons, and quantum field theory [PDF]
Physical Review B, 2021 We consider XY-spin degrees of freedom on an fcc lattice, such that the system respects some subsystem global symmetry. We then gauge this global symmetry and study the corresponding $U(1)$ gauge theory on the fcc lattice. Surprisingly, this $U(1)$ gauge theory is dual to the original spin system.

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.

Learning Lattice Quantum Field Theories with Equivariant Continuous Flows [PDF]
SciPost Physics, 2022 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.

Quantum algorithms for open lattice field theory [PDF]
Physical Review A, 2021 Certain aspects of some unitary quantum systems are well-described by evolution via a non-Hermitian effective Hamiltonian, as in the Wigner-Weisskopf theory for spontaneous decay. Conversely, any non-Hermitian Hamiltonian evolution can be accommodated in a corresponding unitary system + environment model via a generalization of Wigner-Weisskopf theory.

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

Bayesian Inference for Contemporary Lattice Quantum Field Theory [PDF]
Proceedings of The 40th International Symposium on Lattice Field Theory — PoS(LATTICE2023), 2023 Bayesian inference provides a rigorous framework to encapsulate our knowledge and uncertainty regarding various physical quantities in a well-defined and self-contained manner.

Trailhead for quantum simulation of SU(3) Yang-Mills lattice gauge theory in the local multiplet basis [PDF]
Physical Review D, 2021 Maintaining local interactions in the quantum simulation of gauge field theories relegates most states in the Hilbert space to be unphysical -- theoretically benign, but experimentally difficult to avoid. Reformulations of the gauge fields can modify the

Quantum mean estimation for lattice field theory
Physical Review D, 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. The algorithm is used to compute $π$ with and without a sign problem, a toy U(1) gauge theory model, and the ...

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 ...
