Lie Bialgebra Structures and Quantization of Generalized Loop Planar Galilean Conformal Algebra

Axioms
In this paper, we analyze the Lie bialgebra (LB) and quantize the generalized loop planar-Galilean conformal algebra (GLPGCA) W(Γ). Additionally, we prove that all LB structures on W(Γ) possess a triangular coboundary.

Hochschild cohomology of the Weyl conformal algebra with coefficients in finite modules [PDF]

Journal of Mathematics and Physics, 2022
In this work, we find Hochschild cohomology groups of the Weyl associative conformal algebra with coefficients in all finite modules. The Weyl conformal algebra is the universal associative conformal envelope of the Virasoro Lie conformal algebra ...

Conformal Symmetries of the Strumia–Tetradis’ Metric

Physical Sciences Forum, 2023
In a recent paper, a new conformally flat metric was introduced, describing an expanding scalar field in a spherically symmetric geometry. The spacetime can be interpreted as a Schwarzschild-like model with an apparent horizon surrounding the curvature ...

Automated handling of complex chemical structures in Z‐matrix coordinates—The chemcoord library

Journal of Computational Chemistry, Volume 44, Issue 5, Page 710-726, February 15, 2023., 2023
We propose an algorithm for a chemically intuitive automatically generated Z‐matrix representation, including reliable back‐and‐forth transformation between coordinate spaces while properly handling linear dependencies. The usefulness of the method is showcased for molecule manipulation and initial guesses of reaction pathways.

High‐order multigrid strategies for hybrid high‐order discretizations of elliptic equations

Numerical Linear Algebra with Applications, Volume 30, Issue 1, January 2023., 2023
Abstract This study compares various multigrid strategies for the fast solution of elliptic equations discretized by the hybrid high‐order method. Combinations of h$$ h $$‐, p$$ p $$‐, and hp$$ hp $$‐coarsening strategies are considered, combined with diverse intergrid transfer operators.

Conformation control of triplet state diffusion in platinum containing polyfluorene copolymers

Journal of Polymer Science, Volume 61, Issue 1, Page 83-93, 1 January 2023., 2023
Abstract The spectral diffusion of singlet and triplet excitons in 9,9‐dioctylfluorene‐based conjugated copolymers is investigated using photoluminescence spectroscopy at both low (5 K) and room temperature (300 K). Inclusion of a N,N‐diphenyl‐4‐(pyridin‐2‐yl)aniline moiety into the polymer backbone allows subsequent cyclometalation with platinum ...

Conformal Interactions Between Matter and Higher‐Spin (Super)Fields

Fortschritte der Physik, Volume 71, Issue 1, January 2023., 2023
Abstract In even spacetime dimensions, the interacting bosonic conformal higher‐spin (CHS) theory can be realised as an induced action. The main ingredient in this definition is the model S[φ,h]$\mathcal {S}[\varphi ,h]$ describing a complex scalar field φ coupled to an infinite set of background CHS fields h, with S[φ,h]$\mathcal {S}[\varphi ,h ...
