Compared to so-far used global heating schemes, which are slow and energy-costly, light-controlled heating, using optical degrees of freedom such as light wavelength, polarisation, and power, allows to implement local, efficient, and fast heating schemes for the use in nanomagnetic computation or to quantify collective emergent phenomena in artificial spin systems. Single-domain nanoscale magnets interacting…
Long Live the Nanolight
An international research team reports that light confined in the nanoscale propagates only in specific directions along thin slabs of molybdenum trioxide, a natural anisotropic 2-D material. Besides its unique directional character, this nanolight propagates for an exceptionally long time, and thus has possible applications in signal processing, sensing and heat management at the nanoscale.…
