... In particular, we predict that the droplet can have a peculiar excitation spectrum containing only a continuum part and very few or no discrete modes (usually associated with collective excitations: surface waves, breathing mode, etc.) This means that starting from an ordinary finitetemperature trap ...

The additivity problem in quantum information theory
... memoryless quantum channels with respect to entangled encodings. Should the additivity fail, this would mean that applying entangled inputs to several independent uses of a quantum channel may result in superadditive increase of its capacity for transmission of classical information. However so far ...

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 ...
