Quantum Physics of Solid State odern physics based on quantum mechanics clarifies interesting phenomena that cannot be explained by classical physics (such as mechanics and electromagnetism). It also provides new inventions that can improve quality of our life in a revolutionary way. Researchers in Quantum Physics of Solid States study fundamental aspects of microscopic properties of solids as well as their applications. They deal with superconductors, semiconductors, dielectrics, and magnets made of both inorganic and organic materials.
Kuroda Lab.
Experimental studies on spin-related properties in solids and material search. We synthesize “quantum” materials such as magnetic semiconductors, quantum dots, topological insulators, clarify their spin-related properties, and also develop novel materials, aiming at applications for spintronics.
Matsuishi Lab.
To explore new optical functionalities, we fabricate and study spectroscopically nano-structured semiconductors such as quantum dots, organic molecular superlattices, organic-inorganic complexes, C60 nanotubes and amorphous. Pressure-induced phenomena of nano-structured materials are also investigated extensively.
Fujioka Lab.
Research on electronic and optical property in strongly correlated electron material and topological material. Searching new quantum phenmena and functions by using stateof-the-art material synthesis technique and spectroscopy.
Marumoto Lab.
The research topics of our group are development, characterization, and controls of performance of new semiconductor devices using functional materials such as conducting π-conjugated polymers and oligomers, perovskite, carbon materials, and transition metal chalcogenides. We investigate the topics by fabricating electronic devices such as solar cells, light-emitting diodes (LEDs), and transistors, and by using characterization methods such as electron spin resonance (ESR), transport, and optics.
Kashiwagi Lab.
We mainly study highly correlated electron systems in solid state physics such as physical properties of oxide high-Tc superconductors, coexistence of magnetism with superconductivity, iron pnictide superconductors, etc., based on high quality single crystals. We also challenge to explore new types of material with exotic physical properties. The discovery of THz LASER radiation in high-Tc superconductor Bi2Sr2CaCu2O8+d is an typical example. This will allow us to develop quantum computing devices and to explore a unprecedented area of research fields in biomedical science and technology in near future.
Minami Lab.
・Non-linear transport properties of quantum para-electric materials ・Terahertz emitting devices employing the intrinsic Josephson junctions in High-Tc superconductors (with Kadowaki Lab.)
Mori Lab.(Ultra-broadband Spectroscopy)
By using ultra-broadband Spectroscopy, we have studied various kinds of disordered materials. Vibration and relaxation dynamics have been investigated on structural phase transitions of ferroelectric crystals and nanoparticles, liquid-glass transitions of oxide glasses and bioprotectants, and denaturation of protein crystals.
