Productive Imagination in Painting from Ricoeur's Point of View [PDF]

open access: yesJournal of Philosophical Investigations, 2023
The study of imagination has always had a significant role in the study of art and aesthetics. And imagination plays a central role in Ricoeur's philosophical system; a subject that has received less attention.

The Scalar, Vector and Tensor Fields in Theory of Elasticity and Plasticity [PDF]

open access: yesTransactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2014
This article is devoted to an analysis of scalar, vector and tensor fields, which occur in the loaded and deformed bodies. The aim of this article is to clarify and simplify the creation of an understandable idea of some elementary concepts and ...

Extremal effective field theories

open access: yesJournal 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 ...

Effective Field Theories

open access: yesParticles, 2020
This paper represents a pedagogical introduction to low-energy effective field theories. In some of them, heavy particles are “integrated out” (a typical example—the Heisenberg–Euler EFT); in some, heavy particles remain but some of their degrees of ...

Regularization in quantum field theories

open access: yesVojnotehnički 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.

Manifestly SL(2, R) Duality-Symmetric Forms in ModMax Theory

open access: yesJournal 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,

Minimal supergeometric quantum field theories

open access: yesPhysics 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.

Balanced Topological Field Theories [PDF]

open access: yes, 1996
We describe a class of topological field theories called ``balanced topological field theories.'' These theories are associated to moduli problems with vanishing virtual dimension and calculate the Euler character of various moduli spaces.

Field Theories for type-II fractons

open access: yesSciPost 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 ...

Quantum quench and thermalization to GGE in arbitrary dimensions and the odd-even effect

open access: yesJournal of High Energy Physics, 2020
In many quantum quench experiments involving cold atom systems the post-quench phase can be described by a quantum field theory of free scalars or fermions, typically in a box or in an external potential.
