Shifting and Variational Properties for Fourier-Feynman Transform and Convolution [PDF]

Journal of Function Spaces, 2015
Shifting, scaling, modulation, and variational properties for Fourier-Feynman transform of functionals in a Banach algebra S are given. Cameron and Storvick's translation theorem can be obtained as a corollary of our result.

Conditional Fourier-Feynman Transforms with Drift on a Function Space

Journal of Function Spaces, 2019
In this paper we derive change of scale formulas for conditional analytic Fourier-Feynman transforms and conditional convolution products of the functions which are the products of generalized cylinder functions and the functions in a Banach algebra ...

Atomic-Scale Insights Into Antisite-Defect-Induced Metallicity in Halide Perovskites. [PDF]

Small
Using an aberration‐corrected scanning transmission electron microscope, we identify that the PbCs antisite defect in CsPbBr3 shortens the Pb─Pb bond by ∼20 pm, and induces local strain and polarization, leading to a semiconductor‐to‐metal transition.

Biosynthesis of Silver Nanoparticles Using Black Pepper (Piper nigrum) Seed Extract and Evaluation of Their Cytotoxicity. [PDF]

Chem Biodivers
This study reports the green biosynthesis of piperine‐functionalized silver nanoparticles from Piper nigrum seed extract, followed by comprehensive physicochemical characterization and in vitro cytotoxic evaluation. The results confirm successful nanocomposite formation and demonstrate a marked enhancement of cytotoxic activity against gastric cancer ...

${\rm MnBr}_2$ on the Graphene on Ir(110) Substrate: Growth, Structure, and Super-Moiré. [PDF]

Small
The study realizes single‐layer MnBr2${\rm MnBr}_2$ via molecular beam epitaxy on graphene on Ir(110), unveiling a unique super‐moiré (“moiré of moirés”) formed by lattices of different symmetries. Remarkably, this super‐moiré is driven by a virtual interaction between non‐contacting layers.

Fourier-Feynman transforms of unbounded functionals on abstract Wiener space

Open Mathematics, 2010
Abstract Huffman, Park and Skoug established several results involving Fourier-Feynman transform and convolution for functionals in a Banach algebra S on the classical Wiener space. Chang, Kim and Yoo extended these results to abstract Wiener space for a more generalized Fresnel class $$ \mathcal{F}_{\mathcal{A}_1 ,\mathcal{A}_2 } $$

A Series Approximation for the Analytic Fourier–Feynman Transform on Wiener Space

Axioms
In this paper, we first establish an evaluation formula to calculate Wiener integrals of functionals on Wiener space. We then apply our evaluation formula to carry out easy an calculation for the analytic Fourier–Feynman transform of the functionals ...

Flow-oriented perturbation theory

Journal of High Energy Physics, 2023
We introduce a new diagrammatic approach to perturbative quantum field theory, which we call flow-oriented perturbation theory (FOPT). Within it, Feynman graphs are replaced by strongly connected directed graphs (digraphs).
