We theoretically study the thermal relaxation of many-body systems under the action of oscillating external fields. When the magnitude or the orientation of a field is modulated around values where the pairwise heat-exchange conductances depend non-linearly on this field, we demonstrate that the time symmetry is broken during the evolution of temperatures over a modulation cycle. We predict that this asymmetry enables a pumping of heat which can be used to cool down faster the system. This…

Fluctuation-electrodynamic theory and dynamics of heat transfer in systems of multiple dipoles

A general fluctuation-electrodynamic theory is developed to investigate radiative heat exchanges between objects that are assumed to be small compared with their thermal wavelength (dipolar

Adiabatic Thermal Radiation Pumps for Thermal Photonics.

TLDR
It is found that appropriately designed adiabatic pumping cycling near diabolic singularities can dramatically enhance the efficiency of the directional energy transfer.

Many-body near-field radiative heat pumping

We introduce a local radiative heat-pumping effect between two bodies in a many-body system, obtained by periodically modulating both the temperature and the position of an intermediate object using

Anisotropic Thermal Magnetoresistance for an Active Control of Radiative Heat Transfer

The discovery that the near-field radiative heat transfer enables to overcome the limit set by Planck’s law holds the promise to have an impact in different nanotechnologies that make use of thermal

Radiative Heat Shuttling.

We demonstrate the existence of a shuttling effect for the radiative heat flux exchanged between two bodies separated by a vacuum gap when the chemical potential of photons or the temperature

Many-body radiative heat transfer theory.

TLDR
The theory extends the standard Polder and van Hove stochastic formalism used to evaluate heat exchanges between two objects isolated from their environment to a collection of objects in mutual interaction and gives a natural theoretical framework to investigate the photon heat transport properties of complex systems at the mesoscopic scale.

Photon Thermal Hall Effect.

TLDR
A near-field thermal Hall effect (i.e., Righi-Leduc effect) in networks of magneto-optical particles placed in a constant magnetic field is predicted, related to a symmetry breaking in the system induced by the magnetic field.

Persistent Directional Current at Equilibrium in Nonreciprocal Many-Body Near Field Electromagnetic Heat Transfer.

TLDR
It is demonstrated that, in thermal equilibrium, a nonreciprocal many-body system in heat transfer can support a persistent directional heat current, without violating the second law of thermodynamics.

Magnetic field control of near-field radiative heat transfer and the realization of highly tunable hyperbolic thermal emitters

We present a comprehensive theoretical study of the magnetic field dependence of the near-field radiative heat transfer (NFRHT) between two parallel plates. We show that when the plates are made of

Thermal rectification and spin-spin coupling of nonreciprocal localized and surface modes

We study the rectification of near-field radiative heat transfer between two InSb nanoparticles due to the presence of nonreciprocal surface modes in a nearby InSb sample when an external magnetic
