Outline of Final Research Achievements

Anharmonic oscillation and its coupling to other degrees of freedom can give rise to emergent phenomena in matters. In this study, we employed a complementary use of synchrotron x-ray and neutron scattering to explore anharmonicity and its effects on physical properties. We revealed importance of anharmonicity in unconventional physical properties, such as superconductivity, heavy-fermion state and quantum criticality in cage compounds, filled skutterudites PrT4Sb12, beta-pyrochlore AOs2O6 and stannide superconductors (Ca,Sr)3T4Sn13 through a detailed investigation of static and dynamical responses. Detailed insights into both phonon and crystal field excitations in vibronic compounds CeAl2 can contribute to establish theoretical model and look for nuclear-magnetic interference effects.
