“…In the holographic approach light/heavy quarks models have different structures of the background phase transition [16,28]. In most of holographic models the background phase transition, see figure 17 A, is related to chiral symmetry breaking [15,22,24,33,34,40,41,44,48,49,51]. Confinement/deconfinement phase transition may be related to background phase transition and may be not, figure 17 B.…”

“…There are different ways to handle with gauge kinetic functions to include magnetic field in holographic model. Coupling functions f 1 and f B in Einstein-dilaton-Maxwell-Maxwell action can be different [36,49] or equal as well [42,43]. Taking the same gauge function is equivalent to a single Maxwell field on special ansatz, producing both chemical potential and external magnetic field.…”

“…Isotropic holographic QCD "bottom-up" models were considered in numerous papers [6]- [55]. These models have been considered to study the confinement/deconfinement phase transition [6-8, 11, 13, 16-21, 23, 31, 32, 35, 38, 49, 53-55], as well as the chiral phase transition [15,22,24,33,34,40,41,44,48,49,51] and also to search for quarkyonic phase transition [37]. One of the popular methods for constructing an HQCD within the "bottom-up" approach is a potential reconstruction method for models with Einsteindilaton-Maxwell action.…”

We present a five-dimensional fully anisotropic holographic model supported by Einstein-dilaton-three-Maxwell action. One of the Maxwell fields provides chemical potential; finite chemical potential values are considered. The second Maxwell field serves for anisotropy, representing real spacial anisotropy of the QGP produced in heavy-ion collisions. The third Maxwell field is related to an external magnetic field. Influence of the external magnetic field on the 5-dim black hole solution and the confinement/deconfinement phase diagram, reconstructing the phase transition curves for heavy quarks, is considered. The effect of the inverse magnetic catalyses is revealed and positions of critical end points are found.

“…It is quite interesting to see that both chiral phase transition and deconfinement phase transition could be well studied from holographic method, motivated by the discovery of the Anti-de Sitter/conformal field theory(AdS/CFT) correspondence [26][27][28]. Besides the topdown brane systems [29][30][31][32][33][34][35][36], in bottom up approach, the Einstein-Maxwell-dilaton(EMD) system [37][38][39][40][41][42][43][44][45][46][47]provides a good starting point to investigate deconfinement phase transition, while the chiral phase transition [48][49][50][51][52][53][54][55][56][57][58] and light meson spectra [59][60][61][62][63][64][65][66][67][68] could be well described in the soft-wall model [69]. The order parameters of both chiral transition and deconfining transition, chiral condensate qq and expectation value of Polyakov loop L respectively, could be easily extracted from holographic dictionary.…”

We investigate rotating effect on deconfinement phase transition in an Einstein-Maxwell-Dilaton (EMD) model in bottom-up holographic QCD approach. By constructing a rotating black hole, which is supposed to be dual to rotating strongly coupled nuclear matter, we investigate the thermodynamic quantities, including entropy density, pressure, energy density, trace anomaly, sound speed and specific heat for both pure gluon system and two-flavor system under rotation. It is shown that those thermodynamic quantities would be enhanced by large angular velocity. Also, we extract the information of phase transition from those thermodynamic quantities, as well as the order parameter of deconfinement phase transition, i.e. the loop operators. It is shown that, in the T − ω plane, for two-flavor case with small chemical potential, the phase transition is always crossover. The transition temperature decreases slowly with angular velocity and chemical potential. For pure gluon system with zero chemical potential, the phase transition is always first order, while at finite chemical potential a critical end point (CEP) will present in the T − ω plane.

“…The thermodynamical properties and phase structure have been studied widely in the holographic QCD model with finite temperature and chemical potential [35][36][37][38][39][40][41][42][43][44][45]. Other interesting and important work in the holographic QCD can be seen in [46][47][48][49][50][51][52][53][54][55][56][57][58][59][60]. The effect of momentum anisotropy on QCD thermodynamics can be seen in [61].…”

We consider the holographic QCD model with a planar horizon in the D dimensions with different consistent metric solutions. We investigate the black hole thermodynamics, phase diagram and equations of state (EoS) in different dimensions. The temperature and chemical potential dependence of the drag force and diffusion coefficient also have been studied. From the results, the energy loss of heavy quark shows an enhancement near the phase transition temperature in D dimensions. This finding illustrates that the energy loss of heavy quark has a nontrivial and non-monotonic dependence on temperature. Furthermore, we find the heavy quark may lose less energy in higher dimension. The diffusion coefficient is larger in higher dimension.
