From Cosmological Cuts to Yang--Mills Wavefunctions in de Sitter Space
Song He, Jiajie Mei, Yuyu Mo
We study tree-level Yang--Mills wavefunctions in four-dimensional de Sitter space using their discontinuities. Cosmological cuts factorize gluon discontinuities into lower-point wa…
Operational Tube-Sector Theory of Quantum State Distinguishability Under Generalized Symmetries
Song He
A variational principle for quantum-state distinguishability is established in many-body systems with generalized symmetries, including noninvertible cases described by fusion cate…
Hidden simplicity in AdS spinning Mellin amplitudes via scaffolding
Song He, Xiang Li, Yuyu Mo +1
We uncover surprising hidden simplicity in Mellin amplitudes for tree-level AdS holographic correlators for spinning operators, such as AdS "gluons" and "gravitons" (spin 1 and 2).…
Loops and legs: ABJM amplitudes from -graphs
Song He, Yao-Qi Zhang
We initiate a systematic study on how to extract planar integrands of (supersymmetric) scattering amplitudes with loops and legs in Aharony-Bergman-Jafferis-Maldacena (ABJM…
