Hydration phase diagram for sodium cobalt oxide Na0.3CoO2*yH2O

M. L. Foo, T. Klimczuk, R. J. Cava

The hydration phase diagram for sodium cobalt oxyhydrate, Na0.3CoO2*yH2O (y=0, 0.6, 1.3), was determined as a function of relative humidity at 298K. It is found that greater than 7…

Local versus non-local information in quantum information theory: formalism and phenomena

Michal Horodecki, Pawel Horodecki, Ryszard Horodecki +4

In spite of many results in quantum information theory, the complex nature of compound systems is far from being clear. In general the information is a mixture of local, and non-lo…
