We present a brief review on the co-evolution between supermassive black holes (SMBHs) and their hosting galaxies. SMBHs have been thought to be the central engine of active galactic nuclei (AGNs) that emit tremendous energy from a very compact region in their nuclei. Although AGNs are observed in only several percent of galaxies, recent observations have shown that almost all of galaxies have a SMBH in their nuclei. It is also found that there is a tight correlation between the SMBH and the bulge masses, suggesting the co-evolution between them. Based on recent observations and theoretical considerations, we discuss what happens in galaxies during the cosmic time.

An atom interferometer has been developed using the magnetic-field-insensitive two-photon transitions between sodium-ground hyperfine states having different signs of the g-factor. Using it, the Berry phase for a whole turn in a conical rotation of the magnetic field has been manifested free from the dynamical phase shift. It was also demonstrated that the time derivative of the evolving Berry phase induces a frequency shift of the resonance transition. The noncyclic Berry phase based on the geodesic rule was realized by returning the magnetic field along a straight line connecting the initial and the final points. These experimental results were compared with the theoretical expectations.

Inflation provides a mechanism of generation of primordial inhomogeneity which is needed for the formation of large-scale structures in our present universe. After the wavelength of generated quantum fluctuations becomes larger than the Hubble horizon, the quantum nature of the fluctuation is expected to be lost and the statistical property of fluctuations is represented by the classical distribution function. This assumption of "quantum to classical transition of primordial fluctuations" must be justified. In this article, we introduce the approach to apprehend the mechanism of quantum to classical transition of primordial fluctuations from the view point of the quantum entanglement.

Transition metal dichalcogenide (TMD) is attracting growing interest as two dimensional crystals beyond graphene. Of particular importance is an optoelectronic functionality based on valleytronics, which is strongly coupled with spintronics through the spin-orbit interactions, making TMD a quite unique system distinct from graphene. In this article, we review our latest findings of novel functionalities in TMD materials combined with field effect transistor device architecture, including electric field induced superconductivity and electrically switchable chiral light source, both of which are missing in graphene.

Spin state and magnetic anisotropy of individual iron(II) phthalocyanine (FePc) molecules attached to Cu(110) and Cu(110)(2×1)-O electrodes were investigated by inelastic electron tunneling spectroscopy with scanning tunneling microscopy (STM-IETS) together with soft X-ray photoelectron spectroscopy. In the IETS spectra of FePc on Cu(110)(2×1)-O, double-step structure appears arising from the excitations between the zero-field-split spin substates of spin triplet. The magnetic-field evolution of the double-step structure shows that the magnetic anisotropy is converted from in-plane to out of plane by the interaction between the molecule and the substrate. In contrast, the spin state of FePc on Cu(110) is converted from spin triplet to the singlet upon the adsorption. These results demonstrate that tuning the interactions at the molecule-substrate interface enables us to control the magnetic properties of magnetic molecule such as spin state and magnetic anisotropy.
