Many-body EFT
I will review the concept of many-body physics with several examples and their connection to hydrodynamics. I will first review the convenientional framework of hydrodynamics and motivate the need of an lagrangian formulation based on the microscopic properties of quantum many-body systems. These quantum properties will naturally lead to constraints on the physical parameters in the effective theory of hydrodynamics. I will describe the main idea of this formalism and present an application of this hydro EFT and its relevance to experiments.
