From Nuclear Matter with Quenched $g_A$ to Compact-Star Matter with a Signal for Emergent Hidden Scale Symmetry Open
An ``unorthodox" idea is developed that the long-standing mystery in nuclear physics of the effective axial-current coupling constant in nuclei, $g_A^{\rm eff}\approx 1$, could be interpreted in terms of an emerging hidden scale symmetry i…

The Quenched gA in Nuclei and Infrared Fixed Point in QCD Open
The possible consequence of an infrared (IR) fixed point in QCD for Nf=2, 3 in nuclear matter is discussed. It is shown in terms of d(ilaton)-χ effective field theory (dχEFT) incorporated in a generalized effective field theory implemented…

Probing for an IR-fixed Point in QCD by Superallowed Gamow-Teller Transitions in Doubly Magic Nuclei Open
This brief note is to point out that the recent measurements at GSI and RIKEN of the superallowed Gamow-Teller transition in the doubly magic closed-shell nucleus $^{100}$Sn could give an indication for a possibly important {\it fundamenta…

Baryons in finite nuclei, nuclear matter and dense compact-star matter are described in terms of Cheshire Cat for QCD. A potential conceptual link, admittedly short in mathematical rigor, between their manifestations is made by what's call…

The Quenched ${g_A}$ Puzzle in Nuclei & Nuclear Matter and "Pseudo-Conformality" in QCD Open
The long-standing puzzle of the quenched $g_A$ in nuclei is shown to have an extremely simple resolution in a renormalization-group (RG) treatment of a hidden local symmetric (HLS) and scale-symmetric (HSS) chiral Lagrangian. It is shown t…

$V_{lowk}$ Renormalization Group Flow, Vector Manifestation and Sound Velocity in Massive Compact Stars Open
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 nucle…

Corrections to Landau Fermi-liquid fixed-point approximation in nonlinear bosonized theory: Application to $g_A^L$ in nuclei Open
We calculated in nonlinear bosonized theory $1/\bar{N}$ corrections to the Landau Fermi-liquid fixed-point (FLFP) axial-vector coupling constant in nuclear matter $g_A^L\approx 1$ to which the Landau parameter $F_1^ω$ predominantly contrib…

Probing Fractional Quantum Hall Sheets in Dense Baryonic Matter Open
Unlike the octet baryons for $N_f=3$, there is no skyrmion coming from the $η^\prime$ meson. It is instead described as a fractional quantum Hall droplet, a pancake or a pita involving a singular $η^\prime$ ring in which Chern-Simons field…

Pseudo-Conformal Sound Speed in the Core of Compact Stars Open
By implementing the putative “hadron-quark continuity” conjectured in QCD in terms of skyrmion-half-skyrmion topological change in an effective field theory for dense matter, we argue that (quasi-)baryons could “masquerade” deconfined quar…

"Pseudo-Conformal" Sound Speed in the Core of Compact Stars Open
We present the argument that "pseudo-conformal" symmetry permeates from low density near nuclear matter to high density in the core of massive neutron stars. As a support of this argument, we describe how the quenched $g_A\approx 1$ in nuc…

The answer is found in the way the hidden scale symmetry involving a dilaton emerges in strong nuclear correlations in nuclear matter. It is suggested that the same mechanism is at the origin at higher densities of the sound speed convergi…
