Thermoplasmonic and near-field heat transfer between metamaterials I

16:40 Invited talk : Non-equilibrium quantum manipulation: from quantum thermal machines to quantum transport

Mauro Antezza

Montpellier University (France)

We will discuss the behavior of one or more elementary quantum systems (atoms, molecules, quantum dots, etc) interacting with a stationary, simple and rich electromagnetic environment out of thermal equilibrium. Particular attention will be devoted to the new features that this system offers toward the possibility to manipulate collective atomic states and leading to improved performances in: creation and protection of entanglement, quantum thermal machines, transport of excitations.

17:00 Invited talk : Exploring and Tailoring Near-Field Thermal Radiation at Extreme Separation

Svetlana V. Boriskina, Vazrik Chiloyan, Poetro L. Sambegoro, Jonathan Tong, Yi Huang, Gang Chen


Theoretical and experimental studies of mechanisms of the near-field thermal radiation enhancement and control reveal contributions from surface polariton waves, morphology-dependent trapped optical modes, as well as material and metamaterial phase transitions. A new theoretical approach based on the lattice dynamics and the microscopic Maxwell equations is presented, which enables bridging the theories of conduction and radiation.

17:20 Invited talk : Thermal self-oscillations in radiative heat exchange

We report the effect of relaxation-type self-induced temperature oscillations in the system of two parallel plates of SiO-2 and VO2 which exchange heat by thermal radiation in vacuum. The non-linear feedback in the self-oscillating system is provided by metal-insulator transition in VO2 . Using the method of fluctuational electrodynamics we show that under the action of an external laser of a constant power, the temperature of VO2 plate oscillates around its phase transition value.

17:40 Invited talk : Near-field heat transfer in moving media

Yu Guo, Zubin Jacob

University of Alberta (Canada)

Resonators fold the path of light by reflections leading to a phase balance and thus constructive addition of propagating waves. However, amplitude decrease of these waves due to incomplete reflection or material absorption leads to a finite quality factor of all resonances. Here we report on our discovery that evanescent waves can lead to a perfect phase and amplitude balance causing an ideal Fabry-Perot resonance condition in spite of material absorption and non-ideal reflectivities.
