The neutron is largely spherical and incompressible in atomic nuclei. These two properties are however challenged in the extreme pressure environment of a neutron star. Our variational computation within the Cornell model of Coulomb gauge QCD shows that the neutron (and also the ∆ baryon) can adopt cubic symmetry at an energy cost of about 150 MeV . Balancing this with the free energy gained by tighter neutron packing, we expose the possible softening of the equation of state of neutron matter.

Cubic Wavefunction Deformation of Compressed Atoms
We hypothesize that in a non-metallic crystalline structure under extreme pressures, atomic wavefunctions deform to adopt a reduced rotational symmetry consistent with minimizing interstitial spaceExpand

From analysis of the light geodesic along the radial direction, an infinite time for light passing through the event horizon of the black hole seems to be an unreasonable physical solution. The sameExpand

A first estimate of triply heavy baryon masses from the pNRQCD perturbative static potential
Within pNRQCD we compute the masses of spin-averaged triply heavy baryons using the now-available NNLO pNRQCD potentials and three-body variational approach. We focus in particular on the role of theExpand
Unified Field Theory and the Configuration of Particles
The Standard Model of particle physics is a theory concerning electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of known subatomic particles. The current formulationExpand
Mass Limit of Neutron Star
The mass limit of neutron star has still remained a mystery. The existing Tolman-Oppenheimer-Volkoff (TOV) equation for calculating the limit always gives different values, by introducing differentExpand

The Charge Structures of Aether and Substance
The hypothesis of the charge structures matter serves as the basis for defining the inner energies of “rest” an electron: Ee=αc/(2πRe)[s﹣1]; a neutrino: En=Eeα3; a proton: Ep=Ee(α-2-3α-1). “Relict”Expand
