(Ref. 24, for example, does not acknowledge Bell’s formulation of local causality, and instead proposes an alternative formulation very different from Bell’s.) It is thus not surprising that many have summarized the implications of Bell’s t ...

Effects of photonic structures on upconversion
... Upconversion of low-energy photons presents an interesting possibility to overcome the Shockley-Queisser-efficiency limit1 of silicon solar cells and make use of the sub-band-gap-photons which are otherwise transmitted through the cell and cannot be used for energy conversion. Using an upconverter m ...

Deformed Generalization of the Semiclassical Entropy
... Wehrl entropy is simply the “classical entropy” (1) of a Wigner-distribution. Indeed, µ(x, p) is a Wignerdistribution DW smeared over an ~ sized region of phase space [21]. The smearing renders µ(x, p) a positive function, even if DW does not have such a character. The semi-classical Husimi probabil ...
