Neutron Skins: Weak Elastic Scattering and Neutron Stars
Juliette M. Mammei, Charles J. Horowitz, Jorge Piekarewicz +2
The recently completed PREX-2 campaign - which measured the weak form factor of lead at an optimal momentum transfer - has confirmed that the neutron skin of lead is relatively lar…
Determination of the Equation of State from Nuclear Experiments and Neutron Star Observations
Chun Yuen Tsang, ManYee Betty Tsang, William G. Lynch +2
With recent advances in neutron star observations, major progress has been made in determining the pressure of neutron star matter at high density. This pressure is constrained by…
Density Dependence of the Symmetry Energy in the Post PREX-CREX Era
Brendan T. Reed, F. J. Fattoyev, C. J. Horowitz +1
The recently published CREX results suggest a rather peculiar picture for the density dependence of the symmetry energy. Whereas PREX favors a large neutron skin thickness in $^{20…
Long Range Plan: Dense matter theory for heavy-ion collisions and neutron stars
Alessandro Lovato, Travis Dore, Robert D. Pisarski +61
Since the release of the 2015 Long Range Plan in Nuclear Physics, major events have occurred that reshaped our understanding of quantum chromodynamics (QCD) and nuclear matter at l…
GW190814: Impact of a 2.6 solar mass neutron star on nucleonic equations of state
F. J. Fattoyev, C. J. Horowitz, J. Piekarewicz +1
Is the secondary component of GW190814 the lightest black hole or the heaviest neutron star ever discovered in a double compact-object system [R. Abbott et al., ApJ Lett., 896, L44…
Insights into nuclear saturation density from parity violating electron scattering
C. J. Horowitz, J. Piekarewicz, Brendan Reed
The saturation density of nuclear matter is a fundamental nuclear physics property that is difficult to predict from fundamental principles. The saturation density is closely…
Fast neutrino cooling of nuclear pasta in neutron stars: molecular dynamics simulations
Zidu Lin, Matthew E. Caplan, Charles J. Horowitz +1
The direct URCA process of rapid neutrino emission can occur in nonuniform nuclear pasta phases that are expected in the inner crust of neutron stars. Here, the periodic potential…
Weak charge and weak radius of C
Oleksandr Koshchii, Jens Erler, Mikhail Gorchtein +5
We present a feasibility study of a simultaneous sub-percent extraction of the weak charge and the weak radius of the C nucleus using parity-violating electron scattering,…
The Elasticity of Nuclear Pasta
M. E. Caplan, A. S. Schneider, C. J. Horowitz
The elastic properties of neutron star crusts are relevant for a variety of currently observable or near-future electromagnetic and gravitational wave phenomena. These phenomena ma…
Domains and defects in nuclear "pasta"
Andre da Silva Schneider, Matt E. Caplan, Don K. Berry +1
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…
Neutron skins and neutron stars in the multi-messenger era
F. J. Fattoyev, J. Piekarewicz, C. J. Horowitz
The historical first detection of a binary neutron star merger by the LIGO-Virgo collaboration [B. P. Abbott et al. Phys. Rev. Lett. 119, 161101 (2017)] is providing fundamental ne…
Quantum Nuclear Pasta and Nuclear Symmetry Energy
F. J. Fattoyev, C. J. Horowitz, B. Schuetrumpf
Complex and exotic nuclear geometries are expected to appear naturally in dense nuclear matter found in the crust of neutron stars and supernovae environment collectively referred…
Neutrino-nucleon scattering in supernova matter from the virial expansion
C. J. Horowitz, O. L. Caballero, Zidu Lin +2
We generalize our virial approach to study the neutral current neutrino response of nuclear matter at low densities. In the long-wavelength limit, the virial expansion makes model-…
Effect of topological defects on "nuclear pasta" observables
A. S. Schneider, D. K. Berry, M. E. Caplan +2
[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 resistivi…
Parking-garage structures in astrophysics and biophysics
C. J. Horowitz, D. K. Berry, M. E. Caplan +2
A striking shape was recently observed for the cellular organelle endoplasmic reticulum consisting of stacked sheets connected by helical ramps. This shape is interesting both for…
The full weak charge density distribution of 48Ca from parity violating electron scattering
Z. Lin, C. J. Horowitz

Swelling of nuclei embedded in neutron-gas and consequences for fusion
A. S. Umar, V. E. Oberacker, C. J. Horowitz +2
Fusion of very neutron rich nuclei may be important to determine the composition and heating of the crust of accreting neutron stars. We present an exploratory study of the effect…
Comment on "Neutron Skin of Pb from Coherent Pion Photoproduction"
A. Gardestig, C. J. Horowitz, Gerald A. Miller
We argue that the reaction mechanism for the coherent pion production is not known with sufficient accuracy to determine the neutron radius of 208Pb to the claimed precision of 0.0…

The dense neutron-rich matter found in supernovae and neutron stars is expected to form complex nonuniform phases referred to as nuclear pasta. The pasta shapes depend on density,…
Pulsar Glitches: The Crust may be Enough

A way forward in the study of the symmetry energy: experiment, theory, and observation
C. J. Horowitz, E. F. Brown, Y. Kim +6
