| Research Abstract |
The aim of this study is to get the direct experimental evidence of Dirac cone satae in 2 dimensional conductor under high pressure beyond 1.5 GPa, which is predicted by the theory of Suzumura group. The Dirac cone state, which is expected to realize under high pressure, is the new concept in condensed matter physics. However, in order to make the direct observation of it, we developed the new system including the development of pressure cell, which enables the transmission of electro-magnetic wave in the THz region because the measurement requires the absorption measurement of the electro-magnetic wave under multi-extreme conditions, such as high pressure, low temperature and high magnetic field. We have succeeded in developing the system which enables the measurement under 1.5 GPa, 4.2K, 10T and frequency beyond 400 GHz. Now we are in the position to make the direct measurement, and the result is expected in near future.
