Description
Recent neutron-star observations and equation-of-state studies incorporating ab initio QCD constraints are placing increasingly stringent constraints on dense matter. In this context, homogeneous color superconductivity has attracted renewed phenomenological interest and has been actively studied in recent years.
On the other hand, inhomogeneous phases remain relatively less explored. Moreover, quantum-geometric effects, which have been actively studied in condensed-matter physics, have not yet been fully incorporated into the study of color superconductivity.
In this work, we combine these two directions and investigate how quantum-geometric corrections modify conventional crystalline color-superconducting phases. In particular, we focus on the dispersion relations of crystal phonons and quantitatively examine their possible impact on neutron-star phenomenology, including collective modes and vortex-pinning dynamics relevant to pulsar glitches.
