Large period spiking andburstingin anexcitable system with memory [PDF]

open access: yesEPJ Web of Conferences, 2023
Excitability in dynamical systems refers to the ability to transition from a resting stationary state to a spiking state when a parameter is varied. It is the mechanism behind spike generation in neurons.

A nanophotonic interferometer

open access: yesNanotechnology, 2023
Abstract The transmission of light through sub-wavelength apertures (zero-mode waveguides, ZMW) in metal films is well-explored. It introduces both an amplitude modulation as well as a phase shift to the oscillating electromagnetic field.

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics. [PDF]

open access: yesNanophotonics
Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly

Full-spectrum nonmetallic plasmonic carriers for efficient isopropanol dehydration

open access: yesNature Communications, 2022
A nonmetallic plasmonic heterostructure of W18O49 nanowires on reduced-graphene oxide is reported for the efficient dehydration of isopropanol to 100% propylene. The energy barrier is found to be reduced under full-spectrum irradiation.
