Long-distance heat transfer between molecular systems through a hybrid plasmonic-photonic nanoresonator

Abstract

We theoretically study a hybrid plasmonic-photonic cavity setup that can be used to induce and control long-distance heat transfer between molecular systems through optomechanical interactions. The structure we propose consists of two separated plasmonic nanoantennas coupled to a dielectric cavity. The hybrid modes of this resonator can combine the large optomechanical coupling of the sub-wavelength plasmonic modes with the large quality factor and delocalized character of the cavity mode that extends over a large distance (∼µm). We show that this can lead to effective long-range heat transport between molecular vibrations that can be actively controlled through an external driving laser.

“…|e k e l |ρ kl |e j e i | = |e i e i |ρ j j (15) These desired terms thus correspond to increasing population in diagonal matrix elements of ρ (due to |e i e i |), in proportion to other diagonal matrix elements of ρ (due to ρ j j ). Then the cross-terms are simplified.…”

“…Examples of such phenomena include, chemical reactions, 1 photo-dissociation, 8 electron transport, 12,13 isomerization, 14 and heat-transfer between molecules. 15 In theoretical works such as this, the properties of the cavity structure are typically translated into parametric values, such as the mode frequency and the vacuum electric field strength, 16,17 entering the model of the system. The influence of these parameters are well studied and generally well understood.…”

Plasmonic-photonic crystal hybrid devices for optical characterization

“…For the theoretical researches toward application, Mahmoud Ashrafi et al studied long-distance heat transfer between two molecular systems which was induced and controlled by optomechanical interactions of a PhC-plasmonic nano-device [63]. Pezeshki et al designed an integrated PhCplasmonic hybrid system for on-chip all-optical switching and reading memory.…”
