Title: Hydrodynamical charge density wave description for transport in the strange metal phase of cuprates

Room: Naustið-Endurmenntun
Time: Wednesday 9th October, 11:00hrs

The mechanism controlling the exotic behavior of the transport properties in the strange metallic phase of high temperature superconductors is one of the main unresolved problems in condensed matter physics. I will discuss our recent paper (1909.07991) where we develop a framework for describing the hydrodynamics of charge density wave (CDW) order in a magnetic field (extending earlier theoretical developments) and where we determine the DC transport coefficients within this formalism. In this work we performed a complete characterization of the DC transport coefficients (including less common ones like transverse thermal conductivity and Nernst effect) of a single crystal of Bi-2201 close to optimal doping and we found complete self-consistent agreement of this data with the CDW model. This suggests CDW order may be sufficient to explain the unusual properties of the strange metal phase of the cuprates.
