Extremal effective field theories
Journal of High Energy Physics, 2021 Effective field theories (EFT) parameterize the long-distance effects of short-distance dynamics whose details may or may not be known. Previous work showed that EFT coefficients must obey certain positivity constraints if causality and unitarity are ...

Regularization in quantum field theories
Vojnotehnički Glasnik, 2022 Introduction/purpose: The principal techniques of regularization schemes and their validity for gauge field theories are discussed. Methods: Schemes of dimensional regularization, Pauli–Villars and lattice regularization are discussed.

Noncommutative field theory [PDF]
Reviews of Modern Physics, 2001 We review the generalization of field theory to space-time with noncommuting coordinates, starting with the basics and covering most of the active directions of research. Such theories are now known to emerge from limits of M theory and string theory, and to describe quantum Hall states.

Minimal supergeometric quantum field theories
Physics Letters B, 2023 We formulate minimal SuperGeometric Quantum Field Theories (SG-QFTs) that allow for scalar-fermion field transformations in a manifestly reparameterisation covariant manner.

Manifestly SL(2, R) Duality-Symmetric Forms in ModMax Theory
Journal of High Energy Physics, 2022 In this paper, we will investigate a manifestly SL(2, R)-invariant structure for the energy-momentum tensor of ModMax theory as a nonlinear modification of Maxwell electrodynamics which includes conformal invariance as well. In the context of this theory,

Field Theories for type-II fractons
SciPost Physics, 2022 We derive an effective field theory for a type-II fracton starting from the Haah code on the lattice. The effective topological theory is not given exclusively in terms of an action; it must be supplemented with a condition that selects physical ...

Effective Field Theories [PDF]
, 1992 Effective field theories encode the predictions of a quantum field theory at low energy. The effective theory has a fairly low ultraviolet cutoff.

Renormalons in integrable field theories
Journal of High Energy Physics, 2020 In integrable field theories in two dimensions, the Bethe ansatz can be used to compute exactly the ground state energy in the presence of an external field coupled to a conserved charge.

FROM EUCLIDEAN FIELD THEORY TO QUANTUM FIELD THEORY [PDF]
Reviews in Mathematical Physics, 1999 In order to construct examples for interacting quantum field theory models, the methods of Euclidean field theory turned out to be powerful tools since they make use of the techniques of classical statistical mechanics. Starting from an appropriate set of Euclidean n-point functions (Schwinger distributions), a Wightman theory can be reconstructed by
