Quantum and classical correlations between players in game theory
Junichi Shimamura, Sahin Kaya Ozdemir, Fumiaki Morikoshi +1
Effects of quantum and classical correlations on game theory are studied to clarify the new aspects brought into game theory by the quantum mechanical toolbox. In this study, we co…
Pre-Processing of Galaxies before Entering a Cluster
Yutaka Fujita
We consider several mechanisms that possibly affect the evolution of disk galaxies in clusters using analytical models based on a hierarchical clustering scenario. We especially fo…
Development of a multi-pixel photon sensor with single-photon sensitivity
Motohiro Suyama, Atsuhito Fukasawa, Junji Haba +8
A multi-pixel photon sensor with single-photon sensitivity has been developed, based on a technology of a hybrid photo-detector (HPD) consisting of a photocathode and a multi-pixel…
X-ray Underluminous Active Galactic Nuclei Relative to Broad Emission Lines in Ultraluminous Infrared Galaxies
Masatoshi Imanishi, Yuichi Terashima
We present X-ray spectra of four ultraluminous infrared galaxies (ULIRGs) with detectable broad near-infrared emission lines produced by active galactic nuclei (AGNs): Mrk 463, PKS…
Monogamy of entanglement and other correlations
Masato Koashi, Andreas Winter
It has been observed by numerous authors that a quantum system being entangled with another one limits its possible entanglement with a third system: this has been dubbed the "mono…
Causal Structure and Gravitational Waves in Brane World Cosmology
Kiyotomo Ichiki, Kouji Nakamura
The causal structure of the flat brane universe of RSII type is re-investigated to clarify the boundary conditions for stochastic gravitational waves. In terms of the Gaussian norm…
