- Abstract summary: We investigate optical forces on dipoles close to a phase-change vanadium dioxide (VO$$) film.
By using Bruggeman theory to describe the effective optical response of the material, we show that, in the near-field regime, the force on the dipoles can change from repulsive just by heating for a selected frequency range.
We demonstrate that the thermal control present in the VO$$ transition clearly shows up in the perpendicular behavior of the optical forces, setting the grounds for alternative approaches to light-matter interactions.

- Abstract: We investigate optical forces on oscillating dipoles close to a phase-change
vanadium dioxide (VO$_2$) film, which exhibits a metal-insulator transition
around $340$ K and low thermal hysteresis. This configuration is related to one
composed of an excited two-level quantum emitter and we employ a classical
description to capture important aspects of the radiation-matter interaction.
We consider both electric and magnetic dipoles for two different
configurations, namely, with the dipole moments parallel and perpendicular to
the VO$_2$ film. By using Bruggeman theory to describe the effective optical
response of the material, we show that, in the near-field regime, the force on
the dipoles can change from attractive to repulsive just by heating the film
for a selected frequency range. We demonstrate that the thermal hysteresis
present in the VO$_2$ transition clearly shows up in the behavior of the
optical forces, setting the grounds for alternative approaches to control
light-matter interactions using phase-change materials.

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.
