| Outline of Final Research Achievements |
I constructed a low-energy hadron effective model based on the gauge-gravity duality in superstring theories, and studied phase structure and changes of hadron properties in nuclear matter at high density. Main results are as follows. I confirmed the existence of half-Skyrmion phase where the spontaneous chiral symmetry breaking has an inhomogeneity in space. I showed that the nucleon mass decreases with density in the low-density region, while it is stable against the density in the half-Skyrmion phase. I also showed that the masses of the pseudoscalar and vector D mesons, which include a charm quark, are degenerate with those of the scalar and axial-vector D mesons.
