Van der Waals Nanoantennas on Gold as Hosts for Hybrid Mie-Plasmonic Resonances
Sam A. Randerson, Panaiot G. Zotev, Xuerong Hu +6
Dielectric nanoresonators have been shown to circumvent the heavy optical losses associated with plasmonic devices, however they suffer from less confined resonances. By constructi…
Weak Localisation Driven by Pseudospin-Spin Entanglement
Frederico Sousa, David T. S. Perkins, Aires Ferreira
At low temperatures, quantum corrections, originating from the interference of the many paths an electron may take between two points, tend to dominate the transport properties of…
