Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition ...
For the Kerker effect to occur, particles need to have electric and magnetic polarizabilities of the same strength. This, however, is very challenging to achieve, as magnetic optical resonances in small particles are relatively ...
Tracking blood flow in the laboratory is an important tool for studying ailments like migraines or strokes and designing new ways to address them. Blood flow is also routinely measured in the clinic, and laser speckle contrast ...
