A01: Physics under Extreme Conditions

Physics under extreme conditions, particularly under high pressures and high magnetic fields, is studied by means of X-ray structure analysis, transport measurements, optical measurements, and magnetic resonance. New functions of molecular conductors are explored through the investigations of mechanism and control of new electronic phases.

A02: Hybrid Systems

New materials and functions are explored in πd-systems, in which conduction electron and localized electron coexist, and control of field-effect doping states and studies of surface states are attempted in organic devices. This aims at controlling conduction electrons by spins and electric fields, and creating new hybrid systems.

A03: New Functions

Various conduction phenomena of molecular conductors, particularly superconductivity, anomalous semiconducting phase, and charge order, are systematically investigated by changing the materials as a parameter, and new electronic phases and new functions are explored. Basic properties are investigated for the study of extreme conditions and hybrid systems, and characterization of new materials is carried out.

A04: New Materials

(1) Syntheses of new materials such as high temperature superconductors, highly conducting matals, and pure organic single component metals, as well as (2) new systems which realize new electonic phases under extreme conditions, are attempted by the use of excellent synthetic techniques.

A05: Theory

Superconductivity and new conduction mechanism of molecular conductors are theoretically investigated on the basis of first principle calculations and many body techniques, and interpretation and prediction of extreme conditions and hybrid systems are attempted.
