“…In this study, we investigate the holographic complexity growth within a D-dimensional QCD model with a planar horizon, utilizing various consistent metric solu-tions previously explored in Refs. [65,66]. This holographic model is an Einstein-Maxwell-scalar system that adopts suitable forms of the scale factor, gauge kinetic function, and optimized parameter values to fit the lattice results and reproduce the confinement/deconfinement transition.…”

In this work, we study the complexity growth in a holographic QCD model at finite temperature and chemical potential in D dimensions according to the complexity equals action conjecture.By inserting a fundamental string as a probe, we can analyze the properties of complexity growth. In this work, we utilize the complexity-action duality to study the evolution of complexity in a holographic QCD model at finite temperature and chemical potential. By inserting a fundamental stringas a probe, we investigated the properties of complexity growth of this Einstein-Maxwell-scalar gravity system, which is affected by the string velocity, chemical potential, and temperature. Our resultsshow that the complexity growth is maximized when the probe string is stationary, and it will decrease as the velocity of the string increases. When the string approaches relativistic velocities, thecomplexity growth always increases monotonically with respect to the chemical potential. Furthermore, we find that the complexity growth can be used to identify phase transitions and crossovers in the model.

In this paper, we consider the Einstein-Maxwell-dilaton holographic model for light quarks with nonzero magnetic field and chemical potential. First, we study the phase diagrams in T−μ and T−B planes. We observe inverse magnetic catalysis which is consistent with the lattice QCD results. We discuss the influence of the magnetic field and chemical potential on the location of the critical end point (CEP). It is found that the magnetic field increases the critical μCEP of the CEP in the T−μ plane and the chemical potential increases the critical BCEP of the CEP in the T−B plane. Second, we discuss the equations of state (EOS) with nonzero magnetic field and chemical potential. We observe that the EOS near the phase transition temperature are nonmonotonic. Then we study the energy loss with a nonzero magnetic field and chemical potential. It is found that the drag force of the heavy quark and jet quenching parameter q^ show an enhancement near the phase transition temperature. The peak values of drag force and q^ are pushed toward lower temperature with increasing B or μ. This phenomenon is consistent with the phase transition temperature decrease with increasing B or μ in this holographic model. Moreover, we find that the heavy quark may lose more energy when it is perpendicular to a magnetic field, which is consistent with the results of the jet quenching parameter.

In this paper, we employ the gauge/gravity duality to study some features of the quark–gluon plasma. For this purpose, we implement a holographic QCD model constructed from an Einstein–Maxwell-dilaton gravity at finite temperature and finite chemical potential. The model captures both the confinement and deconfinement phases of QCD and we use it to study the effect of temperature and chemical potential on a heavy quark moving through the plasma. We calculate the drag force, Langevin diffusion coefficients and also the jet quenching parameter, and our results align with other holographic QCD models and the experimental data.
