Local equilibrium temperatures for the electromagnetic field and the particle's dipole moment are assumed, using a relativistic formulation of the fluctuation-dissipation theorem. Two examples illustrate radiative friction forces: a particle moving through a homogeneous radiation background and above a planar interface. Previous results for arbitrary relative velocities are recovered in a compact way.}, language = {en} } @article{BenAbdallahMessinaBiehsetal.2013, author = {Ben-Abdallah, Philippe and Messina, Riccardo and Biehs, Svend-Age and Tschikin, Maria and Joulain, Karl and Henkel, Carsten}, title = {Heat superdiffusion in plasmonic nanostructure networks}, series = {Physical review letters}, volume = {111}, journal = {Physical review letters}, number = {17}, publisher = {American Physical Society}, address = {College Park}, issn = {0031-9007}, doi = {10.1103/PhysRevLett.111.174301}, pages = {5}, year = {2013}, abstract = {The heat transport mediated by near-field interactions in networks of plasmonic nanostructures is shown to be analogous to a generalized random walk process. The existence of superdiffusive regimes is demonstrated both in linear ordered chains and in three-dimensional random networks by analyzing the asymptotic behavior of the corresponding probability distribution function. We show that the spread of heat in these networks is described by a type of Levy flight. The presence of such anomalous heat-transport regimes in plasmonic networks opens the way to the design of a new generation of composite materials able to transport heat faster than the normal diffusion process in solids.}, language = {en} }
