Employing the AdS/QCD correspondence the graviton potential is adjusted in a bottom-up approach. Lattice QCD data for the equation of state at non-zero temperature serve as input. Transport coefficients follow then without further assumptions or fine tuning.

Recently, a significant amount of attention is payed in the literature to the proposals for experimental observation of the so-called "Unruh effect" and "Unruh radiation", in particular via application of the state-of-the-art laser facilities. In the papers [1-4] we have reconsidered the original derivation [5] of the Unruh effect. This "effect" originates essentially due to splitting of the...

In this talk we will discuss interesting aspects of QED in an intense magnetic field in the context of nonperturbative QED. We show that thanks to the magnetic catalysis of chiral symmetry breaking (i) there is a few percent increase in the electron mass around $10^{15}$ Gauss, the typical magnetic fields on the surface of young neutron stars, and (ii) the magnetized QED vacuum is stable for...

The photon polarization tensor is the central object in an effective theory describing photon propagation in the quantum vacuum. It accounts for the vacuum fluctuations of the underlying theory, and in the presence of external electromagnetic fields, gives rise to such striking phenomena as vacuum birefringence and dichroism. For homogeneous magnetic fields it is explicitly known at one-loop...
