Polaritonic quantization in nonlocal polar materials [PDF]

open access: yesThe Journal of Chemical Physics, 2022
In the Reststrahlen region, between the transverse and longitudinal phonon frequencies, polar dielectric materials respond metallically to light, and the resulting strong light–matter interactions can lead to the formation of hybrid quasiparticles termed surface phonon polaritons.

Anisotropic Purcell Effect and Quantum Interference in Fractal Aggregates of Nanoparticles

open access: yesPhotonics, 2023
We study theoretically the emergence of an anisotropic Purcell factor in random two-dimensional fractal aggregates of nanoparticles. These nanoparticles can either be metallic nanoparticles made of silver, which exhibit surface plasmon resonances, or ...

A Review of Polarization-Sensitive Materials for Polarization Holography [PDF]

open access: yesMaterials, 2020
Polarization holography has the unique capacity to record and retrieve the amplitude, phase, and polarization of light simultaneously in a polarization-sensitive recording material and has attracted widespread attention. Polarization holography is a noteworthy technology with potential applications in the fields of high-capacity data storage ...

Dynamic Nuclear Polarization in battery materials

open access: yesSolid State Nuclear Magnetic Resonance, 2022
The increasing need for portable and large-scale energy storage systems requires development of new, long lasting and highly efficient battery systems. Solid state NMR spectroscopy has emerged as an excellent method for characterizing battery materials. Yet, it is limited when it comes to probing thin interfacial layers which play a central role in the

High Surface Phonon-Polariton in-Plane Thermal Conductance along Coupled Films

open access: yesNanomaterials, 2020
Surface phonon-polaritons (SPhPs) are evanescent electromagnetic waves that can propagate distances orders of magnitude longer than the typical mean free paths of phonons and electrons. Therefore, they are expected to be powerful heat carriers capable of

Color-Switchable Polar Polymeric Materials [PDF]

open access: yesACS Applied Materials & Interfaces, 2019
Spiropyran is an important mechanophore, which has rarely been incorporated as a cross-linker in polar polymer matrices, limiting its applications in innovative mechanochromic devices. Here, three spiropyrans with two- or three-attachment positions were synthesized and covalently bonded in polar poly(hydroxyethyl acrylate) (PHEA), to achieve color ...
