Research in String Theory

拟议的研究涉及各种处于弦/M理论、场论和宇宙学领域的前沿课题。重点是弦理论的宇宙学后果。将在Horava-Witten理论中对热学宇宙学进行研究。弦宇宙学的模型，如M理论的哥德尔宇宙，以及解决弦理论中不可能实现德西特空间的问题，都将被研究。我们还将研究快子凝聚导致的时空衰变。基于我最近的发现，费米液体的普适性类是由K理论来分类的，这让人想起D-膜，我打算分析弦理论的非相对论方面。

The proposed research involves various topics that are at the cutting edge of the fields of string/M-theory, field theory and cosmology. The focus is on cosmological consequences of string theories. Investigations will be made on Ekpyrotic cosmology in the Horava-Witten theory. Models of string cosmology such as the Godel universe of M-theory as well as addressing the problem of the impossibility of realizing de Sitter space in string theory will be investigated. The decay of space-time as a result of tachyon condensation will also be investigated. Based on my recent discovery that universality classes of Fermi liquids are classified by K-theory, which is reminiscent of D-branes, I intend to analyze nonrelativistic aspects of string theory.
