Holographic confinement in inhomogeneous backgrounds

Inhomogeneous holographic thermalization

The sudden injection of energy in a strongly coupled conformal field theory and its subsequent thermalization can be holographically modeled by a shell falling into anti-de Sitter space and forming a black brane. For a homogeneous shell, Bhattacharyya and Minwalla were able to study this process analytically using a weak field approximation. Motivated by event-by-event fluctuations in heavy ion...

The Holographic Principle for General Backgrounds

We aim to establish the holographic principle as a universal law, rather than a property only of static systems and special space-times. Our covariant formalism yields an upper bound on entropy which applies to both open and closed surfaces, independently of shape or location. It reduces to the Bekenstein bound whenever the latter is expected to hold, but complements it with novel bounds when g...

QED Effective Actions in Inhomogeneous Backgrounds: Summing the Derivative Expansion

The QED effective action encodes nonlinear interactions due to quantum vacuum polarization effects. While much is known for the special case of electrons in a constant electromagnetic field (the Euler-Heisenberg case), much less is known for inhomogeneous backgrounds. Such backgrounds are more relevant to experimental situations. One way to treat inhomogeneous backgrounds is the ”derivative exp...

Stringy effect of the holographic correspondence for Dp-brane backgrounds

Based on the holographic conjecture for superstrings on Dp-brane backgrounds and the dual (p + 1)-dimensional gauge theory (0 ≤ p ≤ 4) given in hep-th/0308024 and hep-th/0405203, we continue the study of superstring amplitudes including string higher modes (n 6= 0). We give a prediction to the two-point functions of operators with large Rcharge J . The effect of stringy modes do not appear as t...
