We investigate the existence of inhomogeneous chiral phases in the quark-meson model with explicit chiral-symmetry breaking. We find that the inhomogeneous region shrinks with increasing pion masses but survives for the physical value of m_pi. The instability towards inhomogeneous matter occurs in the scalar channel, while pseudoscalar modes are disfavored.

    Using approximate renormalization group methods, the authors map phase diagrams of Z3 spin and gauge models and find that only chiral spin models and their duals show an infinite Devil's flower family of inhomogeneous...

  2. How neutron star properties disfavor a nuclear chiral density wave

    nucl-th 2024-11 conditional novelty 6.0 of 10

    Within this nucleon-meson model, a chiral density wave in neutron star cores is only stable for equations of state too soft to support observed two-solar-mass pulsars, predicting isotropic cores.
