Gyroid phase in nuclear pasta.
Nuclear matter is considered to be inhomogeneous at subnuclear densities that are realized in supernova cores and neutron star crusts, and the structures of nuclear matter change from spheres to cylinders, slabs, cylindrical holes, and spherical holes as the density increases. In this Letter, we discuss other possible structures, that is, gyroid and double-diamond morphologies, which are period...
متن کاملNuclear pasta structure in hot neutron stars
Structure of cold and hot dense matter at subnuclear densities is investigated by quantum molecular dynamics (QMD) simulations. Obtained phase diagrams show that the density of the phase boundaries between the different nuclear structures decreases with increasing temperature due to the thermal expansion of nuclear matter region. At subnuclear densities, nuclear matter exhibits the coexistence ...
متن کاملGyroid and Gyroid-Like Surfaces
where k1 and k2 are the principal curvatures. These surfaces are called intermaterial dividing surfaces (IMDS).Beside a number of unconnected periodic arranged IMDSs (e.g. spheres, lamellae and cylinders), multicontinuous triply periodic surfaces exist which are of particular interest, see Chap. 1. A bicontinuous (tricontinuous) triply periodic IMDS separates space into two (three) regions, for...
متن کاملThermodynamic properties of nuclear “pasta” in neutron star crusts
Equilibrium phase diagrams for neutron star matter at subnuclear densities are obtained at zero temperature. Spherical, rod-like and slab-like nuclei as well as spherical and rod-like nuclear bubbles are taken into account by using a compressible liquid-drop model. This model is designed to incorporate uncertainties in the nuclear surface tension and in the proton chemical potential in a gas of...
متن کاملFormation of Nuclear “Pasta” in Cold Neutron Star Matter
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 respect to perturbations inducing fission and proton clustering. The nonspherical nuclei are found to be stable against these perturbations, implying the possibility that the size of the stellar region containing such nuc...
