Mode-dependent Emission Thresholds and Frequencies in Metal Nanoparticles within Gain-enhanced Media
Karen Caicedo, Nicole Recalde, Milena Mora +5
We present a mode-resolved analysis of emission thresholds in metal nanoparticles embedded within an infinite gain medium, using Mie scattering theory as a rigorous framework. Focu…

Gain-Assisted Optomechanical Position Locking of Metal/Dielectric Nanoshells in Optical Potentials
Paolo Polimeno, Francesco Patti, Melissa Infusino +6
We investigate gain-assisted optical forces on dye-enriched silver nanoshell in the quasi-static limit by means of a theoretical/numerical approach. We demonstrate the onset of non…

Faster calculations of optical trapping using neural networks trained by T-matrix data: an application to micro and nanoplastics
Shadi Rezaei, David Bronte Ciriza, Abdollah Hassanzadeh +5
We employ neural networks to improve and speed up optical force calculations for dielectric particles. The network is first trained on a limited set of data obtained through accura…
