Photoreceptor adaptation ensures appropriate visual responses during changing light conditions and contributes to colour constancy. We used behavioural tests to compare UV-sensitivity of budgerigars after adaptation to UV-rich and UV-poor backgrounds. In the latter case, we found lower UV-sensitivity than expected, which could be the result of photon-shot noise corrupting ...

The spatial structure of light with Orbital Angular Momentum, or "twisted light", closely resembles the shape of atomic wavefunctions. It could therefore make symmetry-forbidden transitions in quantum dots possible. However, the vanishing intensity in the center of an OAM beam usually makes this effect weak. Here we show a plasmonic ...
