Outline of Final Research Achievements

In this research project, we apply the derivative expansion and 1/D expansion methods to construct new type of AdS black hole solutions and derive the fundamental properties of strongly coupled field theories via the AdS/CFT duality. By constructing a rotating black droplet solution from the derivative expansion, we showed that the Cauchy horizon is quantum mechanically unstable for a strongly coupled field theory. By applying the 1/D expansion method to the polarized AdS black branes, we derived a new set of effective equations describing the dynamics of the polarized black branes and showed that the solution is stable against linear perturbation. In strongly coupled field theories, we also showed that the averaged null energy with appropriate weight cannot be negative for spatially compact universes or evaporating black hole spacetime.

Academic Significance and Societal Importance of the Research Achievements

一般相対性理論では特異点定理やトポロジー定理など、宇宙のダイナミックスを理解する上で基礎となる諸定理が存在する。これらの定理は通常の古典的な場で成立している光的エネルギー条件の非負性から導かれるが、量子効果によって破れる可能性があることが指摘されていた。曲がった時空での通常の場の理論では、それを解析する手段がほとんどなかったが、AdS/CFT双対性に着目した本研究において、大域的に平均化された光的エネルギー条件が満たされることを示した学術的意義は大きい。また、曲がった時空における場の理論の解析的手法を与えた本研究によって、今後量子効果も含めた時空のダイナミックスに大きな進展が見込まれる。
