DESCRIPTION:At typical central densities of neutron stars (5 - 10 times nu
 clear density ) the nucleon is resolved and therefore composite.It is then
  unwise to use purely nucleonic or hadronic degres of freedom as has been 
 custom. On the other hand\, perturbative QCD applies at much higher densit
 y. We use a renormalizable effective Lagrangian \, that is QCD coupled to 
 a chiral multiplet ( pi \, sigma) which can interpolate between all desiti
 es. It yields the nucleon as a quark soliton and also admits several inter
 esting phases at high density.\nThe ground state for the core of a neutron
  star is found to be a pion condensate ( for 2 flavour matter ). This grou
 nd state is anisotropic and lines up the magnetic moments of the constitue
 nt quarks to dynamically yield strong magnetic fields of typical strength 
 of those found in pulsars.\n\nhttps://indico.ific.uv.es/event/1200/
