“…By analytic solving the full backreacted Einstein equation, meson Regge spectrum and phase structure in QCD were studied. In [28][29][30][31][32][33][34][35][36][37][38][39], a probe open string in an AdS background was studied. In [26], probe open strings were added in the holographic QCD model for heavy quarks and the behavior of open strings has been studied in the black hole background.…”

We study confinement-deconfinement phase transition in a holographic soft-wall QCD model. By solving the Einstein-Maxwell-scalar system analytically, we obtain the phase structure of the black hole backgrounds. We then impose probe open strings in such background to investigate the confinementdeconfinement phase transition from different open string configurations under various temperatures and chemical potentials. Furthermore, we study the Wilson loop by calculating the minimal surface of the probing open string world-sheet and obtain the Cornell potential in confinement phase analytically.

“…In the framework of holography, by breaking the conformal symmetry of the original AdS/CFT correspondence in different ways, efforts towards realistic holographical description of non-perturbative physics of QCD, such as hadron physics and hot/dense QCD matter [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50], have been made both in top-down approaches and in bottom-up approaches(see Refs. [51][52][53][54][55] for reviews).…”

Chiral phase transition for three-flavor N f = 2 + 1 QCD with m u = m d = m s is investigated in a modified soft-wall holographic QCD model. Solving temperature dependent chiral condensates from equations of motion of the modified soft-wall model, we extract the quark mass dependence of the order of chiral phase transition in the case of N f = 2 + 1, and the result is in agreement with the "Columbia Plot", which is summarized from lattice simulations and other non-perturbative methods. First order phase transition is observed around the three flavor chiral limit m u/d = 0, m s = 0, while at sufficient large quark masses it turns to be a crossover phase transition. The first order and crossover regions are separated by a second order phase transition line. The second order line is divided into two parts by the m u/d = m s line, and the m s dependence of the transition temperature in these two parts are totally contrast, which might indicate that the two parts are governed by different universality classes.

“…where S N G is the string world-sheet action bounded by the loop C at the boundary of an AdS space. In [24][25][26][27][28][29][30][31][32][33][34][35], a probe open string in an AdS background was considered. The two ends of the open string are attached to the boundary of AdS background and behave as a quark-antiquark pair.…”

We study confinement-deconfinement phase transition for heavy quarks in a soft wall holographic QCD model. We consider a black hole background in an EinsteinMaxwell-scalar system and add probe open strings to the background. Combining the various configurations of the open strings and the phase structure of the black hole background itself, we obtain the confinement-deconfinement phase diagram for heavy quarks in the holographic QCD model.
