(2014)PHYSICAL REVIEW D.89(1). Mark abstract In a recent paper Y. Hidaka and A. Yamamoto [Phys. Rev. D 87, 094502 (2013)] claim-using both analytical and numerical approaches-that the charged rho mesons cannot condense in the vacuum subjected to a strong magnetic field. In this Comment we point out that both the analytical and numerical results of this paper are consistent with the inhomogeneous rho-meson condensation. Furthermore, we show that the numerical results of the paper support the presence of the expected (in quenched lattice QCD) crossover transition driven by the rho-meson condensation. Finally, we stress that the inhomogeneous rho-meson condensation is consistent with both Vafa-Witten and Elitzur theorems.
