    "abstract": "We estimate exclusive density and asymmetry parameter dependent dispersion\nrelations of various charged states of pions in asymmetric nuclear matter. The\npossibility of matter induced mixing of $\\pi^0$ with $\\eta$ is clearly exposed\nwith the further mass modification of $\\pi^0$ meson due to mixing. Asymmetry\ndriven mass splitting and mixing amplitude are of the same order as the\ncorresponding values in vacuum. Closed form analytic results for the mass\nshifts and dispersion relations with and without mixing are presented.\nFurthermore, we discuss the sensitivity of our results on the scalar mean field\nwithin the framework of Quantum Hadrodynamics.",
