Is nuclear matter a solid or liquid?

Click For Summary
SUMMARY

Nuclear matter, particularly in the context of neutron stars, exhibits characteristics that suggest it possesses shear strength, contrary to the behavior of an ideal gas or fermi gas. The discussion highlights that nuclear matter, defined as matter devoid of free electrons, is influenced by repulsive nuclear forces and gravity. While traditional models may liken it to a fermi gas, the extreme conditions in neutron stars indicate a significant shear strength, warranting further exploration of current nuclear matter theories.

PREREQUISITES
  • Understanding of nuclear physics principles
  • Familiarity with fermi gas models
  • Knowledge of neutron star composition and behavior
  • Basic grasp of atomic structure and nuclear forces
NEXT STEPS
  • Research the properties of neutron stars and their shear strength
  • Study current theories of nuclear matter and their implications
  • Explore advanced fermi gas models in nuclear physics
  • Investigate the role of nuclear forces in determining matter states
USEFUL FOR

Physicists, astrophysicists, and students of nuclear physics interested in the properties of nuclear matter and its applications in understanding neutron stars.

Managed to get through a Ph.D. in nuclear physics without covering nuclear matter calculations (or I just don't recall it). My question is does nuclear matter have any shear strength, or is it like an ideal gas? What little I see of elementary calculations it's like a fermi gas so one would expect no shear stresses to speak of.

What are you calling nuclear matter? All ordinary matter consists of atoms with nuclei and electrons.
 
Okay, nuclear matter is a thing people study like for neutron stars and such where there are no free electrons. In ancient time (before quarks were more of a certainty) it's an ##A = \infty## where, ##A## is the atomic number nucleus, held together by a repulsive nuclear force and gravity. My question is does the current nuclear matter theory predict such stuff have a shear strength or is it more like a fermi gas?
