Abstract given by the source: The microscopic origin of high critical temperature superconductors (HTS) remains a mystery which continues to fascinate the scientific community. In these materials the superconductivity emerges from the "strange metal phase" that has properties that cannot be accounted for by a Fermi liquid theory. In the strange metal conventional quasiparticle excitations are missing and the resistivity has a peculiar linear in temperature behaviour, in the entire temperature range, contradicting established theories. These facts challenge our common sense of transport and scattering processes in metals, and instead points towards a regime ruled by hydrodynamics and determined by an extremely fast local thermalization time of the electronic system, induced by strong entanglement. In this proposal we will design a range of experiments using YBCO nanodevices to reveal hydrodynamic transport in HTS. The idea is also to learn how the electron entanglement works and how it can be tuned by studying heavily strained nm thick thin films in high magnetic field. Finally we will search for a nematic superconductivity to learn if/how local orders, in the strange metal phase, reflects in the superconducting condensate. Demonstrating a strongly entangled quantum matter in HTS, will place our pioneering project at the forefront to guide the search and synthesis of new materials and advanced devices, thus opening a new chapter in condensed matter physics.
