| contents | We investigate the combined effects of rotation and finite quark chemical potential on inhomogeneous chiral condensation and the chiral phase diagram within the soft-wall holographic QCD model. Using the five-dimensional AdS-RN metric, we study the spatial profile of the chiral condensate and the resulting $T - Ω$ phase diagram under Neumann and Dirichlet boundary conditions. Increasing $Ω$ induces strong spatial inhomogeneity: the condensate is suppressed more strongly near the edge than at the center, and vanishes at the boundary when $Ω$ exceeds a critical value. The chemical potential $μ$ acts as a global suppression factor, reducing the condensate magnitude without altering the spatial pattern. The $T - Ω$ phase diagrams are investigated for different chemical potentials .For the case $μ$ = 0, they are also studied at different distances from the rotation axis. It is found that both $Ω$ and $μ$ lower the chiral phase transition temperature, and their suppression effects are additive. In a rotating system, the critical temperature becomes position-dependent, decreasing with increasing distance from the rotation axis. These findings reveal a rich, spatially dependent phase structure in rotating QCD matter, relevant for non-central heavy-ion collisions. |
