Title: Thermal Radiation Force and Torque on Moving Nanostructures with Anisotropic Optical Response
Authors: Juan R. Deop-Ruano, Alejandro Manjavacas,
Abstract summary: We show that moving nanostructures with an anisotropic optical response experience a lateral force and a torque that substantially modify their trajectory. These phenomena emerge from the additional coupling between the electromagnetic field components polarized parallel and perpendicular to the trajectory.

Abstract: Nanoscale objects moving relative to a thermal radiation bath experience a drag force due to the imbalance in their interaction with the blue- and redshifted components of the electromagnetic field. Here, we show that, in addition to this drag force, moving nanostructures with an anisotropic optical response experience a lateral force and a torque that substantially modify their trajectory. These phenomena emerge from the additional coupling between the electromagnetic field components polarized parallel and perpendicular to the trajectory, enabled by the anisotropic response of the nanostructure. This work unveils the intricate dynamics of anisotropic nanostructures moving in a thermal radiation bath.

Directional spontaneous emission in photonic crystal slabs [49.1574468325115]
Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations. One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them. Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.

Control of the Radiative Heat Transfer in a Pair of Rotating Nanostructures [77.34726150561087]
We investigate the simultaneous transfer of energy and angular momentum in a pair of rotating nanostructures. We demonstrate that, due to the rotation of the nanostructures, the radiative heat transfer between them can be increased, decreased, or even reversed with respect to the transfer that occurs in absence of rotation. This work unravels the unintuitive phenomena arising from the simultaneous transfer of energy and angular momentum in pairs of rotating nanostructures.

Nonequilibrium Casimir effects of nonreciprocal surface waves [52.12351460454646]
We show that an isotropic dipolar particle in the vicinity of a substrate made of nonreciprocal plasmonic materials can experience a lateral Casimir force and torque. We connect the existence of the lateral force to the asymmetric dispersion of nonreciprocal surface polaritons and the existence of the lateral torque to the spin-momentum locking of such surface waves.
