DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HoloTube/14/
 ">Coherent and incoherent transport in holographic models with spontaneous
 ly broken translations</a>\nby Alexander Krikun (Nordita) as part of HoloT
 ube: Applied holography webinars\n\n\nAbstract\nIn holography it is relati
 vely easy to construct the models which break translation symmetry either 
 explicitly\, or spontaneously\, or both. AC transport in these models has 
 a few interesting features\, which were in focus for the past few years\, 
 including the gapped “pseudo-Goldstone” mode\, the metal — Mott insu
 lator transition\, the residual incoherent conductivity and the contributi
 on of the gapped coherent peak in DC conductivity due to “phase relaxati
 on”. It is particularly interesting to study these features in detail\, 
 since they might have a direct representation in the experimental data on 
 cuprates and doped Mott insulators. I will overview the subject and presen
 t several recent observations in models with either helical or periodic ho
 lographic lattices\, which shed some light on the physics behind these int
 eresting features.\n
