Formation of Nuclear "Pasta" in Supernovae
Gentaro Watanabe, Hidetaka Sonoda, Toshiki Maruyama +3
In supernova cores, nuclear "pasta" phases such as triangular lattice of rod-like nuclei and layered structure of slab-like nuclei are considered to exist. However, it is still unc…
Phase diagram of nuclear "pasta" and its uncertainties in supernova cores
Hidetaka Sonoda, Gentaro Watanabe, Katsuhiko Sato +2
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 cr…
Simulation of Transitions between "Pasta" Phases in Dense Matter
Gentaro Watanabe, Toshiki Maruyama, Katsuhiko Sato +2
Calculations of equilibrium properties of dense matter predict that at subnuclear densities nuclei can be rodlike or slablike. To investigate whether transitions between phases wit…
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…
Structure of cold nuclear matter at subnuclear densities by Quantum Molecular Dynamics
Gentaro Watanabe, Katsuhiko Sato, Kenji Yasuoka +1
Structure of cold nuclear matter at subnuclear densities for the proton fraction , 0.3 and 0.1 is investigated by quantum molecular dynamics (QMD) simulations. We demonstrat…
Microscopic Study of Slablike and Rodlike Nuclei: Quantum Molecular Dynamics Approach
Gentaro Watanabe, Katsuhiko Sato, Kenji Yasuoka +1
Structure of cold dense matter at subnuclear densities is investigated by quantum molecular dynamics (QMD) simulations. We succeeded in showing that the phases with slab-like and r…
Microscopic Study of Nuclear "Pasta" by Quantum Molecular Dynamics
Gentaro Watanabe, Katsuhiko Sato, Kenji Yasuoka +1
Structure of cold dense stellar matter at subnuclear densities is investigated with quantum molecular dynamics (QMD). We succeeded in showing that the phases with slab-like and rod…
Formation of Nuclear "Pasta" in Cold Neutron Star Matter
Kei Iida, Gentaro Watanabe, Katsuhiko Sato
Formation and decay of rod-like and slab-like nuclei, as may be encountered in the outer parts of neutron stars, are examined within a zero-temperature stability analysis with resp…
Effects of hyperons on the dynamical deconfinement transition in cold neutron star matter
Kei Iida, Katsuhiko Sato
The influence of the presence of hyperons in dense hadronic matter on the quantum nucleation of quark matter is examined at low temperatures relevant to neutron star cores. We calc…
