Constraints on holographic QCD phase transitions from PTA observations
Song He, Li Li, Sai Wang +1
The underlying physics of QCD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition,…
Holographic study of higher-order baryon number susceptibilities at finite temperature and density
Zhibin Li, Jingmin Liang, Song He +1
The cumulants of baryon number fluctuations serve as a good probe for experimentally exploring the QCD phase diagram at finite density, giving rise to characteristic fluctuation pa…
The ABJM Amplituhedron
Song He, Yu-tin Huang, Chia-Kai Kuo
In this paper, we take a major step towards the construction and applications of an all-loop, all-multiplicity amplituhedron for three-dimensional planar Chern-Simo…
Pseudo entropy of primary operators in /-deformed CFTs
Song He, Jie Yang, Yu-Xuan Zhang +1
In this work, we investigate the time evolution of the pseudo-(Rényi) entropy after local primary operator quenches in 2D CFTs with -deformation. Using perturbatio…
Jumpstarting (elliptic) symbol integrations for loop integrals
Song He, Yichao Tang
We derive an algorithm for computing the total differentials of multi-loop integrals expressed as one-fold integrals of multiple polylogarithms, which can involve square roots of p…
Holographic torus correlators of stress tensor in
Song He, Yi Li, Yun-Ze Li +1
In the context of , we investigate holographic correlators of the stress tensor of a conformal field theory (CFT) on a torus in this work. To calculate the correla…
Emergent unitarity, all-loop cuts and integrations from the ABJM amplituhedron
Song He, Chia-Kai Kuo, Zhenjie Li +1
We elaborate on aspects of a new positive geometry proposed recently, which was conjectured to be the four-point amplituhedron for ABJM theory. We study generalized unitarity cuts…
Cutting the traintracks: Cauchy, Schubert and Calabi-Yau
Qu Cao, Song He, Yichao Tang
In this note we revisit the maximal-codimension residues, or leading singularities, of four-dimensional -loop traintrack integrals with massive legs, both in Feynman parameter s…
Phase diagram of holographic thermal dense QCD matter with rotation
Yan-Qing Zhao, Song He, Defu Hou +2
We study the rotation effects of the hot and dense QCD matter in a non-perturbative regime by the gauge/gravity duality. We use the gravitational model that is designated to match…
