Outline of Final Research Achievements

Various interesting phenomena occur aound the space-time horizons through which information flows in one direction. Examples are Hawking radiation from black hole horizons, thermal fluctuations in de Sitter universe, and Unruh effects for a uniformly accelerated observers. In this project, we investigated those thermal phenomena in the space-time with horizons. In particular, we have shown the second law of black hole by applying the so called fluctuation theorem developped in statistical physics. We also proved that quantum radiation emanates from a uniformly accelerated observer in addition to the classical Larmor radiation, and that it originates from the entanglement of the Minkowski vacuum between the left and the right Rindler wedges. Finally we have discussed the quantum vacuum energy in the de Sitter universe as a candidate of the dark energy.
