Creative Science and EngineeringⅠ FeaturesⅡ History and ProfileⅢ RequirementsAdvanced Science and EngineeringFundamental Science and EngineeringCONTENTS◆ Theory of Condensed Matter PhysicsIn the field of condensed matter physics, we try to clarify and understand the structures and the behaviors of materials and physical systems from microscopic scales to mesoscopic and macroscopic scales, and try to establish their concrete and universal theories by making full use of quantum mechanics, statistical mechanics, etc. The research themes that are currently conducted by the members of this research area include:(1) Interdisciplinary studies on pattern formation and collective behavior in physical, chemical, biological, and social systems, from the viewpoints of statistical physics and nonlinear dynamics. (2) Theoretical studies on low temperature many-body phenomena, including superconductivity, superfluidity, charge density waves, macroscopic tunneling effects, etc. (3) Studies on applied and fundamental physics of nonlinear and chaotic dynamics, quantum and wave chaos, and transport in many-particle systems. (4) Theoretical studies on various quantum phenomena occurring in the microscopic and mesoscopic scales, and on the emergent quantum technologies making use of quantum correlations and entanglements. (5) Theoretical studies on emergent phenomena and device functionalities of magnets, ferroelectrics and strongly correlated materials.◆ Condensed Matter PhysicsCondensed matter physics is a basis of core-technologies for modern industry. Condensed matter physics area at Waseda provides a variety of lecture courses including soft matter physics, laser physics, surface and interface physics, strongly correlated electron physics, optical process in solids, and low-dimensional physics, and also spans a wide range of research on condensed matter. The research theme of each group in condensed matter physics area is as follows: (1) Studies on physical and chemical phenomena occurred in a material and on a surface, such as diffusion of atoms/ions and reduction/oxidation processes. Development of conceptually new devices and systems, such as for neuromorphic computing systems, based on the studies is also carried out. In the studies, instruments such as STM, SEM, LEED, Semiconductor Parameter Analyzer, and EB-deposition system are used. (2) Spectroscopic studies on correlated electrons in the bulk or at the surface of solids. We aim to find novel quantum states or functionalities due to electronic correlation by means of photoemission or x-ray spectroscopy and contribute to development of new energy materials.(3) Attosecond and ultra-fast spectroscopy. We develop intense, ultra-short laser pulses with the wavelength from infrared to soft-Xray to study fast electron dynamics in an atom and molecule. In addition, we develop the new experimental approaches to image fast dynamics of an electron wave function or molecular orbital with attosecond time-resolution.(4) Exploring new physics through new materials. We seek to synthesize new materials including transition metal oxides as strongly correlated electron systems, grow new crystals, and find 113113
