A family of deformed black branes is employed to examine the confinement/deconfinement phase transition in AdS/QCD. The holographic entanglement entropy (HEE) plays the role of the order parameter driving the confinement/deconfinement phase transition. The binding energy of quark-antiquark bound states and the critical length that makes a null variation of the HEE, together with the critical temperature separating the deconfined quark-gluon plasma to the confined hadronic phase, are discussed in the deformed black brane background, matching current experimental hadronic data.

“…Anisotropic stellar configurations are naturally addressed by several gravitational decoupling procedures, which is a sharp apparatus that can be used in a wide range to derive new analytical solutions to Einstein's coupled system of field equations [3][4][5]. Although the gravitational decoupling method is a spontaneous extension of the minimal geometrical deformation [6][7][8][9][10][11][12][13][14], which is also an important setup to study stars and black holes on fluid branes [15][16][17], gravitational decoupled methods do not necessarily depend on any higher-dimensional background, consisting of a genuine and well-established 4dimensional framework. The gravitational decoupling was comprehensively applied to the study and analysis of several compact stellar configurations, based on an appropriate modification of the stress-energy-momentum tensor that enters Einstein's field equations, beyond the Schwarzschild term [18][19][20][21].…”

Gravitational decoupled compact polytropic hybrid stars are here addressed in generalized Horndeski scalar-tensor gravity. Additional physical properties of hybrid stars are scrutinized and discussed in the gravitational decoupling setup. The asymptotic value of the mass function, the compactness, and the effective radius of gravitational decoupled hybrid stars are studied for both cases of a bosonic and a fermionic prevalent core. These quantities are presented and discussed as functions of Horndeski parameters, the decoupling parameter, the adiabatic index, and the polytropic constant. Important corrections to general relativity and generalized Horndeski scalar-tensor gravity, induced by the gravitational decoupling, comply with available observational data. Particular cases involving white dwarfs, boson stellar configurations, neutron stars, and Einstein–Klein–Gordon solutions, formulated in the gravitational decoupling context, are also scrutinized.

In this paper, we explore a modified black brane within AdS spacetime, characterized by the Lagrangian density 1 q arcsin(qR) − 2Λ. Due to the absence of an analytic solution, we approach the Einstein equations using a perturbative method, extending our analysis to the second order in q. Subsequently, we compute the ratio of shear viscosity to entropy density. Our results suggest that the KSS Bound is not saturated in this model.
