Radiative heat transfer between metallic gratings using adaptive spatial resolution
Riccardo Messina, Antonio Noto, Brahim Guizal +1
We calculate the radiative heat transfer between two identical metallic one-dimensional lamellar gratings. To this aim we present and exploit a modification to the widely-used Four…
Excitation injector in an atomic chain: long-ranged transport and efficiency amplification
Pierre Doyeux, Riccardo Messina, Bruno Leggio +1
We investigate the transport of energy in a linear chain of two-level quantum emitters ("atoms") weakly coupled to a blackbody radiation bath. We show that, simply by displacing on…
Strongly coupled near-field radiative and conductive heat transfer between planar objects
Riccardo Messina, Weiliang Jin, Alejandro W. Rodriguez
We study the interplay of conductive and radiative heat transfer (RHT) in planar geometries and predict that temperature gradients induced by radiation can play a significant role…
Exact formulas for radiative heat transfer between planar bodies under arbitrary temperature profiles: modified asymptotics and sign-flip transitions
Riccardo Messina, Weiliang Jin, Alejandro W. Rodriguez
We derive exact analytical formulas for the radiative heat transfer between parallel slabs separated by vacuum and subject to arbitrary temperature profiles. We show that, dependin…
Hyperbolic waveguide for long-distance transport of near-field heat flux
Riccardo Messina, Philippe Ben-Abdallah, Brahim Guizal +2
Heat flux exchanged between two hot bodies at subwavelength separation distances can exceed the limit predicted by the blackbody theory. However this super-Planckian transfer is re…
General formulation of coupled radiative and conductive heat transfer between compact bodies
Weiliang Jin, Riccardo Messina, Alejandro W. Rodriguez
We present a general framework for studying strongly coupled radiative and conductive heat transfer between arbitrarily shaped bodies separated by sub-wavelength distances. Our for…
Quantum thermal machine acting on a many-body quantum system: role of correlations in thermodynamic tasks
Pierre Doyeux, Bruno Leggio, Riccardo Messina +1
We study the functioning of a three-level thermal machine when acting on a many-qubit system, the entire system being placed in an electromagnetic field in a stationary out-of-ther…
Nonequilibrium Casimir-Polder plasmonic interactions
Nicola Bartolo, Riccardo Messina, Diego A. R. Dalvit +1
We investigate how the combination of nonequilibrium effects and material properties impacts on the Casimir-Polder interaction between an atom and a surface. By addressing systems…
