Hydrodynamic Cooperons in Electron Fluids: Schwinger--Keldysh Derivation and Quantum Corrections to Magnetoresistance
Alberto Cortijo
We develop a Schwinger--Keldysh effective theory for quantum-interference corrections in a two-dimensional electron system in the hydrodynamic regime. Starting from the clean hydro…

Quantum Interference Corrections in Electron Hydrodynamics
Alberto Cortijo
We show that quantum-interference corrections in an electron fluid are tightly constrained by hydrodynamic Ward identities: charge and momentum conservation protect the …

Quantum Altermagnetic Instability in Disordered Metals
Alberto Cortijo
The possibility of a zero temperature, altermagnetic instability in anisotropic two dimensional electron systems in the diffusive regime is analyzed, in the presence and absence of…
