The correlated motion of flocks is an example of global order emerging from local interactions. An essential difference with respect to analogous ferromagnetic systems is that flocks are active: ...

How it works: the wave in the foreground is an illustration of the phase of an out-of-equilibrium Bose-Einstein condensate in a 1D cavity, which belongs to the Kardar-Parisi-Zhang universality class.

Three different papers by three different groups on the same theme back-to-back in Nature? That is unusual. Yes, which is why they caught my eye. The papers all look rather interesting: they are about ...

Vinod M. Menon, Professor of Physics & Chair - Photonics Track, City College of New York, will give a talk on “Exciton-polaritons: From manipulating quantum materials to out-of-equilibrium condensates ...
