Vlowk Renormalization group flow, vector manifestation and sound velocity in massive compact stars
Abstract
The VlowkVlowk-renormalization group approach on the surface of Fermi liquid for nuclear matter to which Tom Kuo made a pioneering contribution at Stony Brook is found to inject the pivotal input in the formulation of the generalized nuclear effective field theory with acronym “GnEFT” applicable to superdense compact-star physics. A topology change in terms of skyrmions and half-skyrmions is shown to play the role of the “putative” hadron-quark continuity conjectured in QCD. Crucially involved are hidden local symmetry and hidden scale symmetry with the vacuum sliding with density in nuclear medium, with the nuclear tensor force emerging as a Landau Fermi-liquid fixed-point quantity. A possibly novel paradigm, a “Cheshire Catism,” in nuclear correlations is suggested.
