“…It is known that the noncommutativity of space coordinates also has an influence on the shape of the phase diagram for the chiral symmetry breaking-chiral symmetry restoration within the framework of the noncommutative deformation of the holographic QCD model at finite temperature [37]. It can be regarded as an example that the noncommutativity of space coordinates reflects physical quantities [38,36].…”

We consider the noncommutative deformation of the finite temperature holographic QCD (Sakai--Sugimoto) model in external electric and magnetic field and evaluate the effect of the noncommutaivity on the properties of the conductor-insulator phase transition associated with a baryon number current. Although the noncommutative deformation of the gauge theory does not change the phase structure with respect to the baryon number current, the transition temperature $T_{c}$, the transition electric field $e_{c}$ and magnetic field $b_{c}$ in the conductor-insurator phase transition depend on the noncommutativity parameter $\theta$. Namely, the noncommutativity of space coordinates has an influence on the shape of the phase diagram for the conductor-insurator phase transition. On the other hand, the allowed range of the noncommutativity parameter can be restricted by the reality condition of the constants of motion.Comment: 25 pages, 8 figures. arXiv admin note: text overlap with arXiv:1310.0393, arXiv:1011.290

“…The holographic duals of noncommutative gauge theories with flavor degrees of freedom have also been constructed by using probe techniques [11]. Employing the holographic description, we have been able to find the noncommutativity is also reflected in the flavor dynamics [36]. It should be emphasized that the noncommutativity can also modify phase diagram as for instance chiral symmetry breaking in the noncommutative gauge theory [37,38].…”

In this paper, we derive the universal (cut-off-independent) part of the holographic entanglement entropy in the noncommutative Yang-Mills theory and examine its properties in detail. The behavior of the holographic entanglement entropy as a function of a scale of the system changes drastically between large noncommutativity and small noncommutativity. The strong subadditivity inequality for the entanglement entropies in the noncommutative Yang-Mills theory is modified in large noncommutativity. The behavior of entropic c-function defined by means of the entanglement entropy also changes drastically between large noncommutativity and small noncommutativity. In addition, there is a transition for the entanglement entropy in the noncommutative Yang-Mills theory at finite temperature.
