Frame dependence of heavy-quark observables in a rotating strongly coupled plasma
Leila Shahkarami, Farid Charmchi
In genuinely rotating holographic backgrounds, Wilson-loop observables are usually constructed for a quark--antiquark pair static with respect to the rotating plasma. We investigat…
Thermodynamic scaling and string dynamics in rotating holographic QCD

We investigate the effect of finite angular velocity on the phase structure and Schwinger pair production in a holographic QCD model based on the Einstein--Maxwell--dilaton framewo…
Schwinger effect in dynamical holographic QCD with a supercritical region
Leila Shahkarami, Farid Charmchi
We study the phase structure of QCD matter using a dynamical Einstein--Maxwell--Dilaton holographic model, using both thermodynamic and dynamical observables. Depending on the warp…
Long-term Oscillations and Universal Behavior in Pulsed Electric Fields
