Critical scaling of the ac conductivity and momentum dissipation

The scaling of the AC conductivity in quantum critical holographic theories at finite density, temperature, and presence momentum dissipation is considered. It shown that there generically an intermediate window frequencies which IR clearly visible.1 MoreReceived 14 August 2020Revised 13 November 2020Accepted 16 2020DOI:https://doi.org/10.1103/PhysRevResearch.3.013028Published by American Physical Society under terms Creative Commons Attribution 4.0 International license.
