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.

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?

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.
