双场论中的T-对偶宇宙学解

T-dual cosmological solutions in double field theory

Robert Brandenberger, Renato Costa, Guilherme Franzmann, Amanda Weltman

摘要:

研究了双场论运动方程耦合物质源后的宇宙学解。假设常数π和施加相对于正则坐标的截面条件导致由动量模主导的宇宙,而施加相对于对偶坐标的截面条件自然导致由动量模主导的宇宙。我们表明,这两个政权的渐近行为相关的T-对偶。这暗示着在每一个体系中定义时钟之间的对偶性,并从欧几里得时间的角度将缠绕模式解释为辐射。

英文摘要:

We investigate the cosmological solutions coming from the double field theory equations of motion after coupling a matter source to them. Assuming constant dilaton and imposing the section condition with respect to the regular coordinates leads to a universe dominated by momentum modes while imposing the section condition with respect to the dual coordinates naturally leads to a universe dominated by momentum modes. We show that both regimes have asymptotic behaviours related by T-duality. This hints towards defining a duality between the clocks considered in each regime and interpreting winding modes as being radiation from the point of view of a Euclidean time.
