Background: The “pasta” phase of nuclear matter may play an important role in the structure and evolution of neutron stars. Recent works suggest nuclear pasta has a high resistivity which could be explained by the presence of long-lived topological defects. The defects act as impurities that decrease thermal and electrical conductivity of the pasta. Purpose: To quantify how topological defects affect transport properties of nuclear pasta and estimate this effect using an impurity parameter Q_…

Domains and defects in nuclear pasta
Nuclear pasta topology is an essential ingredient to determine transport properties in the inner crust of neutron stars. We perform semi-classical molecular dynamics simulations of nuclear pasta for
The nucleonic thermal conductivity of “pastas” in neutron star matter
Abstract This investigation explores the nucleonic thermal conductivity of nuclear star matter as it undergoes the “topological” transition to the “pasta” regime, and further down to the solid-liquid
The effect of the energy functional on the pasta-phase properties of catalysed neutron stars
Nuclear pasta, that is an inhomogeneous distribution of nuclear matter characterised by non-spherical clustered structures, is expected to occur in a narrow spatial region at the bottom of the inner
Application of superconducting-superfluid magnetohydrodynamics to nuclear “pasta” in neutron stars
I consider a mixture of superconducting and superfluid nuclear liquids of protons coupled to the ultrarelativistic electron gas and neutrons. In the magnetohydrodynamic (MHD) approximation, the
Superfluidity in nuclear systems and neutron stars
Abstract.Nuclear matter and finite nuclei exhibit the property of superfluidity by forming Cooper pairs. We review the microscopic theories and methods that are being employed to understand the basic
Elasticity of Nuclear Pasta.
TLDR
The results show that nuclear pasta may be the strongest known material, perhaps with a shear modulus of 10^{30}  ergs/cm^{3} and a breaking strain greater than 0.1.
“Parking-garage” structures in nuclear astrophysics and cellular biophysics
A striking shape was recently observed for the endoplasmic reticulum, a cellular organelle consisting of stacked sheets connected by helical ramps [Terasaki et al., Cell 154, 285 (2013)]. This shape
Fluctuations in the composition of nuclear pasta in symmetric nuclear matter at finite temperature
The equilibrium distributions of the different pasta geometries and their linear sizes are calculated from the mean field Gibbs energy functional in symmetric nuclear matter at finite temperature.
Phases of dense matter in compact stars
Formed in the aftermath of gravitational core-collapse supernova explosions, neutron stars are unique cosmic laboratories for probing the properties of matter under extreme conditions that cannot be
Colloquium: Astromaterial science and nuclear pasta
We define `astromaterial science' as the study of materials in astronomical objects that are qualitatively denser than materials on earth. Astromaterials can have unique properties related to their
