Two-Loop Superstrings on Orbifold Compactifications

Kenichiro Aoki, Eric D'Hoker, D. H. Phong

The two-loop chiral measure for superstring theories compactified on $\bZ_2$ reflection orbifolds is constructed from first principles for even spin structures. This is achieved by…

Phases of hot nuclear matter at subnuclear densities

Gentaro Watanabe, Katsuhiko Sato, Kenji Yasuoka +1

Structure of hot dense matter at subnuclear densities is investigated by quantum molecular dynamics (QMD) simulations. We analyze nucleon distributions and nuclear shapes using two…

Moduli space of Fedosov structures

Stanislav Dubrovskiy

We consider the space of germs of Fedosov structures at a point, together with the group of origin-preserving diffeomorphisms acting on it. We calculate dimensions of moduli spaces…

Complete homochirality induced by the nonlinear autocatalysis and recycling

Yukio Saito, Hiroyuki Hyuga

A nonlinear autocatalysis of a chiral substance is shown to achieve homochirality in a closed system, if the back-reaction is included. Asymmetry in the concentration of two enanti…

V445 Puppis -- Helium nova on a massive white dwarf

Mariko Kato, Izumi Hachisu

The 2000 outburst of V445 Puppis shows unique properties, such as absence of hydrogen, enrichment of helium and carbon, slow development of the light curve with a small amplitude t…

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…
