“…In this paper we consider the non-susy D3 brane or, to be precise, a finite temperature version of that solution in type IIB string theory [20]. It is known that like BPS D3 brane, non-susy D3 brane also has a decoupling limit [21,22] and therefore, gives a gravity dual of a non-supersymmetric finite temperature gauge theory in the decoupling limit.…”

Like BPS D3 brane, the non-supersymmetric (non-susy) D3 brane of type IIB string theory is also known to have a decoupling limit and leads to a non-supersymmetric AdS/CFT correspondence. The throat geometry in this case represents a QFT which is neither conformal nor supersymmetric. The 'black' version of the non-susy D3 brane in the decoupling limit describes a QFT at finite temperature. Here we first compute the entanglement entropy for small subsystem of such QFT from the decoupled geometry of 'black' non-susy D3 brane using holographic technique. Then we study the entanglement thermodynamics for the weakly excited states of this QFT from the asymptotically AdS geometry of the decoupled 'black' non-susy D3 brane. We observe that for small subsystem this background indeed satisfies a first law like relation with a universal (entanglement) temperature inversely proportional to the size of the subsystem and an (entanglement) pressure normal to the entangling surface. Finally we show how the entanglement entropy makes a cross-over to the thermal entropy at high temperature.

Large-N thermal QCD laboratories like strongly coupled QGP (sQGP) require not only a large t'Hooft coupling but also a finite gauge coupling [1]. Unlike almost all top-down holographic models in the literature, holographic large-N thermal QCD models based on this assumption, therefore necessarily require addressing this limit from M theory. Using the UV-complete top-down type IIB holographic dual of large-N thermal QCD as constructed in [2] involving a fluxed resolved warped deformed conifold, its delocalized type IIA S(trominger)-Y(au)-Z(aslow) mirror as well as its M-theory uplift constructed in [3], in [4], the type IIB background of [2] was shown to be thermodynamically stable. We also showed that the temperature dependence of DC electrical conductivity mimics a one-dimensional Luttinger liquid, and the requirement of the Einstein relation (ratio of electrical conductivity and charge susceptibility equal to the diffusion constant) to be satisfied requires a specific dependence of the Ouyang embedding parameter on the horizon radius. Any strongly coupled medium behaves like a fluid with interesting transport properties. In [5], we addressed these properties by looking at the scalar, vector and tensor modes of metric perturbations and solve Einstein's equation involving appropriate gauge-invariant combination of perturbations as constructed in [6]. Due to finite string coupling, we obtained the speed of sound, the shear mode diffusion constant and the shear viscosity η (and η s ) upto (N)ext to (L)eading (O)rder in N. The NLO terms in each of the coefficients serve as a the non-conformal corrections to the conformal results.Another interesting result for the temperature dependence of the thermal (and elec-1

The holographic complexity of a 'black' non-susy D3-brane is computed. The difference in the holographic complexity between this geometry in the Fefferman-Graham coordinates and that of the AdS 5 geometry is obtained for a strip type subsystem. This is then related to the changes in the energy and the entanglement entropy of the system. We next take the high temperature limit of the change in complexity and observe that it scales with the temperature in the same way as the holographic entanglement entropy. The crossover of the holographic complexity to its corresponding thermal counterpart is similar to the corresponding crossover of the holographic entanglement entropy in the high temperature limit. We further repeat the analysis for N = 4 super Yang-Mills theory and observe a similar behaviour.
