$V_{lowk}$ Renormalization Group Flow, Vector Manifestation and Sound Velocity in Massive Compact Stars
Abstract
The $V_{lowk}$-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 ``G$n$EFT" 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 (HQC)" conjectured in QCD. Crucially involved are hidden local symmetry (``HLS") and hidden scale symmetry (``HSS") 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.
