¡Enhorabuena! 👏👏👏

🎺🎺 #PLASMONICA2025 has finally started! Alejandro Manjavacas (Theoretical #Nanophotonics group in @iqf-csic.bsky.social, Madrid) kicked it off with an invited talk on the "Collective lattice resonances in complex arrays of nanostructures".

Using dyadic Green’s tensor formalism, we demonstrate state-independent perfect antibunching and identify geometric zeros near reflective interfaces.

In our last work with
@aifernand.bsky.social, Blas Durá has developed a theoretical framework to study spatially-resolved second-order correlations in quantum emitter dimers.

While temporal and spectral correlations have been extensively studied, the spatial structure of these correlations remains comparatively underexplored.

Photon correlations are foundational to quantum optics, underpinning phenomena such as bunching, antibunching, and two-photon interference.

4/ This means that the motion of a nanostructure in a thermal radiation bath is richer than previously thought—with implications for nanomechanics, optomechanics, and even nonequilibrium thermodynamics.

3/ These effects arise because the nanostructure's anisotropy couples the field components polarized parallel and perpendicular to the trajectory. This extra coupling leads to the new force and torque that wouldn’t exist for isotropic objects.

2/ We show that, besides drag, such nanostructures experience a lateral force and a torque that can significantly alter their trajectory.

1/ Nanoscale objects moving in a thermal radiation bath experience drag due to the Doppler shift of the electromagnetic field. But what happens when these objects have an anisotropic optical response?

Our latest work, "Thermal radiation force and torque on moving nanostructures with anisotropic optical response," is out in Physical Review Letters!

This work opens new pathways for scalable, efficient nanoscale lasers, advancing the integration of nanophotonics into miniaturized optical devices.

Our system is metal-free, significantly simplifying fabrication while maintaining strong optical performance. The architecture supports low-threshold multiband lasing even in the presence of fabrication inhomogeneities.

High-refractive-index 2D photonic structures for robust low-threshold multiband lasing High-refractive-index (HRI) dielectrics are gaining increasing attention as building blocks for compact lasers. Their ability to simultaneously support both electric and magnetic modes provides greate...

In our last paper in Nanoscale Horizons, together with the group of A. Mihi @icmabcsic.bsky.social, we study a 2D photonic architecture for lasing consisting of an array of holes in a polymer matrix coated with a high-index dielectric
