The large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from individual galaxies to galaxy ...
Resonant optical phenomena in metals and dielectrics have profound applications in many fields. The nanoscale confinement allows for unpreceded control of light-matter interaction at surfaces and interfaces, manipulating ...
