The Hydrotope in the Water-Wave Action
Qu Cao, Song He, Jirong Jing +1
The Hydrotope gives a geometric representation of tree-level water-wave amplitudes with two negative spatial momenta as the volume of a hyperplane slice of a box. We trace the orig…
Tropical and Stringy Integrals for In-In Correlators
Song He, Xiang Li, Yong-Xiang Su +1
We introduce tropical and stringy integrals for fixed-graph contributions to cosmological in-in correlators of conformally coupled scalars. The full-time representation factorizes…
Planar loop integrands from cuts in dimensions
Fan Zhu, Song He, Zhenqi Han
We present a direct reconstruction formula for planar loop integrands from -dimensional generalized unitarity cuts in any colored theory. The reconstruction combinatorics is sep…
Bootstrapping Giant Graviton Correlators
Song He, Canxin Shi, Yichao Tang +1
We develop bootstrap methods for mixed heavy-light four-point correlators in super-Yang--Mills theory at large , where …
