Unraveling an Ultrafast Electron Transport Mechanism in a Photocatalytic “Micromachine” for Their Potential Light Harvesting Applications

Micromachines, 2023
Following the seminal discovery of Richard Feynman, several micromachines have been made that are capable of several applications, such as solar energy harvesting, remediation of environmental pollution, etc.

Relationships among transforms, convolutions, and first variations

International Journal of Mathematics and Mathematical Sciences, 1999
In this paper, we establish several interesting relationships involving the Fourier-Feynman transform, the convolution product, and the first variation for functionals F on Wiener space of the form F(x)=f(〈α1,x〉,…,〈αn,x〉),

Generalized Analytic Fourier-Feynman Transform of Functionals in a Banach Algebra ℱA1,A2a,b

Journal of Function Spaces and Applications, 2013
We introduce the Fresnel type class ℱA1,A2a,b. We also establish the existence of the generalized analytic Fourier-Feynman transform for functionals in the Banach algebra ℱA1,A2a,b.

Convergence in $L^p$ for Feynman path integrals [PDF]

, 2015
We consider a class of Schrodinger equations with time-dependent smooth magnetic and electric potentials having a growth at infinity at most linear and quadratic, respectively.

Power-counting theorem for staggered fermions [PDF]

, 2006
Lattice power-counting is extended to QCD with staggered fermions. As preparation, the difficulties encountered by Reisz's original formulation of the lattice power-counting theorem are illustrated.

A Rotation of Admixable Operators on Abstract Wiener Space with Applications

Journal of Function Spaces and Applications, 2013
We investigate certain rotation properties of the abstract Wiener measure. To determine our rotation property for the Wiener measure, we introduce the concept of an admixable operator via an algebraic structure on abstract Wiener space.

Comment on "Summing One-Loop Graphs at Multi-Particle Threshold"

, 1992
The propagator of a virtual $\phi$-field with emission of $n$ on-mass-shell particles all being exactly at rest is calculated at the tree-level in $\lambda \phi^4$ theory by directly solving recursion equations for the sum of Feynman graphs.

Regularization of energy-momentum tensor correlators and parity-odd terms [PDF]

, 2015
We discuss the problem of regularizing correlators in conformal field theories. The only way to do it in coordinate space is to interpret them as distributions.

Natural renormalization [PDF]

, 1996
A careful analysis of differential renormalization shows that a distinguished choice of renormalization constants allows for a mathematically more fundamental interpretation of the scheme.
