| Research Abstract |
Fundamental research on electronic properties of various systems provides us the key for the development of modern technology. In this research project, we have studied an organic compound,α-(BEDT-TTF)_2I_3, where electrons obey the relativistic Dirac equation under pressure in spite of the fact that the velocity of electrons is much slower than the speed of light. We have formulated the theory describing the electronic transport properties of this system under magnetic field, and have explained anomalous temperature and magnetic field dependence of the resistivity.
