A hydrodynamical description for magneto-transport in the strange metal phase of Bi-2201

Understand

High temperature superconductors are strongly coupled systems which present a complicated phase diagram with many coexisting phases.

• This makes it difficult to understand the mechanism which generates their singular transport properties.
• Hydrodynamics, which mostly relies on the symmetries of the system without referring to any specific microscopic mechanism, constitutes a promising framework to analyze these materials.
• In this paper we show that in the strange metal phase of the cuprates, a whole set of transport coefficients are described by a universal hydrodynamic framework once one accounts for the effects of quantum critical charge density waves.
