【 摘 要 】

We briefly argue the concept of a quantum domain and propose its detection using X-ray inelastic scattering and X-ray coherent anti-Stokes Raman scattering (CARS). The quantum domain is defined as a spatial region of which the phase state is converted to a different one from that in the background. In a case where photoinduced phase transitions are allowed to exhibit, such a domain has a relatively low excitation energy and is expected to be detected experimentally. Especially the X-ray inelastic scattering and the CARS are attractive methods, since they can give information of both the momentum and the energy.
