On the well-posedness of a class of McKean Feynman-Kac equations
We analyze the well-posedness of a so called McKean Feynman-Kac Equation (MFKE), which is a McKean type equation with a Feynman-Kac perturbation. We provide in particular weak and strong existence conditions as well as pathwise uniqueness conditions ...

A broadband terahertz polarization rotator consisting of twistingly stacked silicon–air metagratings is designed based on the polarization guiding effect and experimentally shown to achieve 90° linear polarization rotation for both TE and TM incidences.

On one-dimensional stochastic control problems: applications to investment models [PDF]
The paper provides a systematic way for finding a partial differential equation that characterize directly the optimal control, in the framework of one?dimensional stochastic control problems of Mayer, with no constraints on the controls.

Development of Heat Engines Powered by Twisted and Coiled Polymer Fiber Actuators
Continuously rotating engines driven by thermally responsive actuating materials can turn waste heat into useful energy. For the first time heat engines operated by twisted and coiled polymer fiber actuators are demonstrated with engine design guided by two simple analytical models.

Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials
THz volume plasmon‐polariton (VPP) propagation through plasmon‐based hyperbolic metamaterials, made of alternating layers of doped and undoped III‐V semiconductors. Abstract The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals.

Enhancing Triplet Excitons Lifetime Through Controlled Intermolecular Interactions
Singlet fission (SF) is investigated in pentacene embedded in a surface‐anchored metal–organic framework, enabling a molecular arrangement inaccessible in pure organic crystals. This architecture changes the singlet fission dynamics significantly and enhances the triplet lifetime by almost four orders of magnitude.

Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we
