Outline of Final Research Achievements

The electrical and thermal conductivities in a warm dense matter are difficult to explain in the conventional theoretical models, neither solid-state physics nor plasma physics. To understand their characteristics, we observe their value and construct the models consistently.
From the obtained results, we found that the ratio between the electrical and thermal conductivities was drastically changed around the degeneracy parameter = 1. We also developed the plasma generation and observation methods by using the pulsed-power discharge. It reveals that the methods provided the characteristics of warm dense matter.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は,低温・高密度プラズマの輸送特性を規格化パラメータによって記述したことで,高エネルギー密度プラズマに関わる学理に新たな知見を与えた.これにより,極端環境下でのプラズマの特性を知ることで,材料のアブレーション時の熱輸送等を知ることができる.これにより,核融合に関わる炉壁の損耗や慣性核融合における爆縮過程の理解,天体プラズマのダイナミクスへの適用が考えられる.また,本研究を通じて新たに開発した高速度撮像方法や液体金属負荷,皮膜負荷などは,多方向同時観測,高エネルギー密度プラズマの高繰り返し応用,遮断現象の制御などに利用することができるため,更なる開発を進める.
