(Phys.org)—Today's photonic and plasmonic devices – the latter based on surface plasmons (a coherent delocalized electron oscillations that exist at the interface between metal and dielectric) and combining the small ...
Ultracold atoms in the so-called optical lattices, which are generated by crosswise superposition of laser beams, have been proven to be one of the most promising tools for simulating and understanding the behaviour of many-body ...
