Incoherent transport for phases that spontaneously break translations (2018)
Journal Article
Donos, A., Gauntlett, J. P., Griffin, T., & Ziogas, V. (2018). Incoherent transport for phases that spontaneously break translations. Journal of High Energy Physics, 2018(4), Article 53. https://doi.org/10.1007/jhep04%282018%29053

We consider phases of matter at finite charge density which spontaneously break spatial translations. Without taking a hydrodynamic limit we identify a boost invariant incoherent current operator. We also derive expressions for the small frequency be... Read More about Incoherent transport for phases that spontaneously break translations.

Diffusion for holographic lattices (2018)
Journal Article
Donos, A., Gauntlett, J. P., & Ziogas, V. (2018). Diffusion for holographic lattices. Journal of High Energy Physics, 2018(3), Article 056. https://doi.org/10.1007/jhep03%282018%29056

We consider black hole spacetimes that are holographically dual to strongly coupled field theories in which spatial translations are broken explicitly. We discuss how the quasinormal modes associated with diffusion of heat and charge can be systemati... Read More about Diffusion for holographic lattices.

Diffusion in inhomogeneous media (2017)
Journal Article
Donos, A., Gauntlett, J. P., & Ziogas, V. (2017). Diffusion in inhomogeneous media. Physical Review D, 96(12), Article 125003. https://doi.org/10.1103/physrevd.96.125003

We consider the transport of conserved charges in spatially inhomogeneous quantum systems with a discrete lattice symmetry. We analyze the retarded two-point functions involving the charges and the associated currents at long wavelengths, compared to... Read More about Diffusion in inhomogeneous media.

Holographic mutual information in global Vaidya-BTZ spacetime (2015)
Journal Article
Ziogas, V. (2015). Holographic mutual information in global Vaidya-BTZ spacetime. Journal of High Energy Physics, 2015(9), Article 114. https://doi.org/10.1007/jhep09%282015%29114

We investigate the evolution of the mutual information between two spatial subsystems in a compact 1+1 dimensional CFT after a quantum quench. To this end, we use the dual holographic process, given by the 2+1 dimensional Vaidya-BTZ spacetime in glob... Read More about Holographic mutual information in global Vaidya-BTZ spacetime.
