Journal of High Energy Physics, 2020 Gauge theory is the framework of the Standard Model of particle physics and is also important in condensed matter physics. As its major non-perturbative approach, lattice gauge theory is traditionally implemented using Monte Carlo simulation ...

Two-particle scattering from finite-volume quantization conditions using the plane wave basis
Journal of High Energy Physics, 2021 We propose an alternative approach to Lüscher’s formula for extracting two-body scattering phase shifts from finite volume spectra with no reliance on the partial wave expansion. We use an effective-field-theory-based Hamiltonian method in the plane wave

Bethe Ansatz equations for the classical A^(1)_n affine Toda field theories [PDF]
, 2014 We establish a correspondence between classical A(1)n affine Toda field theories and An Bethe Ansatz systems. We show that the connection coefficients relating specific solutions of the associated classical linear problem satisfy functional relations of ...

Anomalous transport phenomena on the lattice
, 2022 The interrelation between quantum anomalies and electromagnetic fields leads to a series of non-dissipative transport effects in QCD. In this work we study anomalous transport phenomena with lattice QCD simulations using improved staggered quarks in the ...

Remarks on the quantum field theory in lattice space. II [PDF]
Communications in Mathematical Physics, 1968 We calculate the Gelfand functionsE(f,g;a) for quantized field φ in lattice space,a being the lattice constant. In the limita → 0 the functionals take on two different forms depending upon the “potential”F[φ] of the lattice Hamiltonian (coupling between different lattice sites not included). IfF[φ] is of a short-range type (see text for definition) the

Algebraic Quantum Field Theory [PDF]
, 2006 Algebraic quantum field theory provides a general, mathematically precise description of the structure of quantum field theories, and then draws out consequences of this structure by means of various mathematical tools -- the theory of operator algebras,

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.

Advanced Engineering Materials, EarlyView.Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Lattice Ising model in a field: E8 scattering theory [PDF]
, 1994 Zamolodchikov found an integrable field theory related to the Lie algebra E8, which describes the scaling limit of the Ising model in a magnetic field. He conjectured that there also exist solvable lattice models based on E8 in the universality class of ...
