Phase diagram of nuclear ``pasta' and its uncertainties in supernova cores (2007)
Sonoda, Hidetaka, Watanabe, Gentaro, Sato, Katsuhiko, Yasuoka, Kenji, Ebisuzaki, Toshikazu
We examine the model dependence of the phase diagram of inhomogeneous nulcear matter in supernova cores using the quantum molecular dynamics (QMD). Inhomogeneous matter includes crystallized matter...

A molecular dynamics simulation of vapor phase nucleation has been performed with 40 000 Lennard-Jones particles for the target gas and 0-160 000 particles for the carrier gas. Three carrier gas...
Impact of nuclear "pasta" on neutrino transport in collapsing stellar cores (2007)
Sonoda, Hidetaka, Watanabe, Gentaro, Sato, Katsuhiko, Takiwaki, Tomoya, Yasuoka, Kenji, Ebisuzaki, Toshikazu
Nuclear ``pasta'', nonspherical nuclei in dense matter, is predicted to occur in collapsing supernova cores. We show how pasta phases affect the neutrino transport cross section via weak neutral...

We performed large-scale molecular-dynamics simulation of nanoscale hydrophobic interaction manifested by the formation of nanobubble between nanometer-sized hydrophobic clusters at constrained...
Simulation of Transitions between "Pasta" Phases in Dense Matter (2004)
Watanabe, Gentaro, Maruyama, Toshiki, Sato, Katsuhiko, Yasuoka, Kenji, Ebisuzaki, Toshikazu
Calculations of equilibrium properties of dense matter predict that at subnuclear densities nuclei can be rodlike or slablike. To investigate whether transitions between phases with non-spherical...
