Adiabatic hydrodynamics: the eightfold way to dissipation
Adiabatic hydrodynamics: the eightfold way to dissipation
Hydrodynamics is the low-energy effective field theory of any interacting quantum theory, capturing the long-wavelength fluctuations of an equilibrium Gibbs densitymatrix. Conventionally, one views the effective dynamics in terms of the conserved currents, which should be expressed via the constitutive relations in terms of the fluid velocity and the intensive …
