Poisson Summation Formula for The Space of Functionals

, 2004
In our last work, we formulate a Fourier transformation on the infinite-dimensional space of functionals. Here we first calculate the Fourier transformation of infinite-dimensional Gaussian distribution $\exp(-πξ\int_{-\infty}^{\infty}α^2(t)dt)$ for $ξ\in{\bf C}$ with Re$(ξ)>0$, $α\in L^2({\bf R})$, using our formulated Feynman path integral ...

Circular‐Polarization‐Sensitive Organic Photodetectors with a Chiral Nanopatterned Electrode Inverse‐Designed by Genetic Algorithm

Advanced Functional Materials, EarlyView.
A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

The Unified Theory of Resonance Energy Transfer According to Molecular Quantum Electrodynamics

Atoms, 2018
An overview is given of the molecular quantum electrodynamical (QED) theory of resonance energy transfer (RET). In this quantized radiation field description, RET arises from the exchange of a single virtual photon between excited donor and unexcited ...

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Dual‐Programmable Architected Magnetic Soft Materials: Tuning Mechano–Electric Responses by Inverse Design

Advanced Functional Materials, EarlyView.
ABSTRACT Materials that can deform, sense, and autonomously generate power in response to wireless magnetic fields, through both magnetic‐actuated shape transformation and charge generation, are an emerging focus in advanced functional materials research.

Applications of Minor-Summation Formula I. Littlewood's Formulas

Journal of Algebra, 1996
A minor-summation formula of a Pfaffian expressing a weighted sum of minors of any rectangular matrix in terms of a single Pfaffian was obtained by \textit{M. Ishikawa} and \textit{M. Wakayama} [Linear Multilinear Algebra 39, No. 3, 285-305 (1995; Zbl 0830.15011)].
