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.

Effective Field Theories and Quantum Chromodynamics on the Lattice
, 2004 We give a selection of results on spectrum and decay constants of light and heavy-light hadrons. Effective field theories relevant for their lattice calculation, namely non-relativistic QCD (NRQCD) for heavy quarks on the lattice and Chiral Perturbation Theory for light quarks, are briefly discussed.

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 ...

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.

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

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.
