Abstract
We demonstrate theoretically that it is possible to exercise coherent control of the temperature in nanostructures by laser fields. In particular we show that by use of nanosecond laser pulses it is possible to induce a temperature distribution on a collection of nanoparticles which can last for up to thousands of nanoseconds before assuming the temperature of the environment. Although the form of the temperature distribution depends on the spatiotemporal control of the optical near field induced by the laser field, it is far from being proportional to the local radiation field at a particular point due to the cooling mechanisms which take place among the nanoparticles. We also show that it is possible to selectively heat a given target nanoparticle with adaptive control of the illuminating laser field without a nanoscale focus.
