Notes on weight-shifting operators and unifying relations for cosmological correlators
Qi Chen, Yi-Xiao Tao
We seek the inverse formulas for the cosmological unifying relation between gluons and conformally coupled scalars. We demonstrate that the weight-shifting operators derived from t…
Differential Operators and Unifying Relations for 1-loop Feynman Integrands from Berends-Giele Currents
Qi Chen, Yi-Xiao Tao
Our work focuses on utilizing the Berends-Giele currents to construct differential operators and unifying relations for 1-loop Feynman integrands. We successfully reproduce the kno…
A Type of Unifying Relation in (A)dS Spacetime
Yi-Xiao Tao, Qi Chen
Unifying relations of amplitudes are elegant results in flat spacetime, but the research on these in (A)dS case is not very rich. In this paper, we discuss a type of unifying relat…
Integrality and Gauge Dependence of Hennings TQFTs
Qi Chen, Thomas Kerler
We provide a general construction of integral TQFTs over a general commutative ring, , starting from a finite Hopf algebra over which is Frobenius and doub…
On the integrality of Witten-Reshetikhin-Turaev 3-manifold invariants
Anna Beliakova, Qi Chen, Thang Le
We prove that the SU(2) and SO(3) Witten-Reshetikhin-Turaev invariants of any 3-manifold with any colored link inside at any root of unity are algebraic integers.
Quantum invariants of 3-manifolds associated to restricted quantum groups
Qi Chen, Chih-Chien Yu, Yu Zhang
We show that the Witten-Reshetikhin-Turaev SU(2) invariant and the Hennings invariant associated to the restricted quantum are essentially the same for rational homology 3-s…
