Holographic QCD equation of state constrained by lattice QCD: neural-ODE for probe-limit and a back-reaction test

Yutian Deng, Mei Huang, Lin Zhang

We study the equation of state (EoS) of QCD matter in a bottom-up holographic setup that combines an Einstein-Maxwell-dilaton (EMD) sector with an improved Karch-Katz-Son-Stephanov…
