On a class of conformal E $$ \mathcal{E} $$ -models and their chiral Poisson algebras

open access: yesJournal of High Energy Physics, 2023
In this paper, we study conformal points among the class of E $$ \mathcal{E} $$ -models. The latter are σ-models formulated in terms of a current Poisson algebra, whose Lie-theoretic definition allows for a purely algebraic description of their dynamics ...

Gauge Symmetry and Howe Duality in 4D Conformal Field Theory Models

open access: yesAdvances in Mathematical Physics, 2010
It is known that there are no local scalar Lie fields in more than two dimensions. Bilocal fields, however, which naturally arise in conformal operator product expansions, do generate infinite Lie algebras.

A SIMPLE DERIVATION OF FINITE-TEMPERATURE CFT CORRELATORS FROM THE BTZ BLACK HOLE

open access: yesActa Polytechnica, 2014
We present a simple Lie-algebraic approach to momentum-space two-point functions of two-dimensional conformal field theory at finite temperature dual to the BTZ black hole.

On Riemannian manifolds endowed with a locally conformal cosymplectic structure

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
We deal with a locally conformal cosymplectic manifold M(φ,Ω,ξ,η,g) admitting a conformal contact quasi-torse-forming vector field T. The presymplectic 2-form Ω is a locally conformal cosymplectic 2-form.

Generalizing the $$\mathfrak {bms}_{3}$$ bms3 and 2D-conformal algebras by expanding the Virasoro algebra

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
By means of the Lie algebra expansion method, the centrally extended conformal algebra in two dimensions and the $$\mathfrak {bms}_{3}$$ bms3 algebra are obtained from the Virasoro algebra.

On realizations of Lie algebras

open access: yesActa Polytechnica
We discuss and compare the main methods for constructing of Lie vector fields from the given Lie algebra structure constants. Generic realizations of three conformal algebras are obtained by the algebraic method and all realizations of the three ...

Advances in Hygroscopic Polymer Gels toward Efficient Atmospheric Moisture Capture and Management

open access: yesAdvanced Science, EarlyView.
This review systematically elaborates on the research progress of hygroscopic polymer gels (HPGs) in the field of atmospheric moisture management, summarizes their hygroscopic mechanisms, construction strategies, and typical multi‐field applications, highlights the urgency of developing moisture‐adaptive HPGs for low‐humidity arid regions, and ...

Poincare gauge gravity from nonmetric gravity

open access: yesNuclear Physics B
We consider general linear gauge theory, with independent solder form and connection. These spaces have both torsion and nonmetricity. We show that the Cartan structure equations together with the defining equation for nonmetricity allow the mixed ...

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR

open access: yesAdvanced Intelligent Discovery, EarlyView.
Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

Coordinate‐ and Spacetime‐Independent Quantum Physics

open access: yesAnnalen der Physik, EarlyView.
This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept
