We study the interplay between chiral and diquark condensates within the framework of the Ginzburg-Landau free energy, and classify possible phase structures of two and three-flavor massless QCD. The QCD axial anomaly acts as an external field applied to the chiral condensate in a color superconductor and leads to a crossover between the broken chiral symmetry and the color superconducting phase, and, in particular, to a new critical point in the QCD phase diagram.

  1. Properties of QCD axion in two-flavor color superconductive matter with massive quarks

    hep-ph 2025-01 conditional novelty 6.0 of 10

    In a two-flavor NJL model with chiral and diquark condensates, the axion mass and quartic coupling increase at the chiral phase transition when color superconductivity is present.

  2. Chiral effective theory of scalar and vector diquarks revisited

    hep-ph 2024-11 conditional novelty 5.0 of 10

    A new term in the chiral diquark Lagrangian is shown to control the mass ordering of pseudoscalar diquarks and to set the threshold at which heavy-baryon decays turn off under chiral restoration.

  3. Spin-charge deconfinement and emergent $\mathrm{AdS}_3$ structure from a self-consistent dressing of Fierz-complete $(1+1)$d Dirac fermions

    hep-th 2026-06 unverdicted novelty 4.0 of 10

    A self-consistent dressing of Fierz-complete (1+1)d Dirac fermions yields spin-charge deconfinement diagnosed by Wilson loops, an emergent sl(2,R) gauge field, and an order-parameter manifold promoted to AdS3 ≅ SL(2,R).
