Artificial crystals of light, consisting of hundreds of thousands of optical microtraps, are routinely created by interfering optical laser beams. These so-called optical lattices act as versatile ...

Abstract: The paper presents a new optical drive system incorporating acceleration disturbance suppression control in the focus actuator. The new system uses a disturbance observer based on modern ...

Cluster algebras and scattering diagrams appear in diverse areas of mathematics and physics including total positivity, Seiberg duality, statistical physics models, noncommutative geometry, tropical ...
