Topological sigma models & dissipative hydrodynamics
Felix M. Haehl, R. Loganayagam, Mukund Rangamani
We outline a universal Schwinger-Keldysh effective theory which describes macroscopic thermal fluctuations of a relativistic field theory. The basic ingredients of our construction…
The Fluid Manifesto: Emergent symmetries, hydrodynamics, and black holes
Felix M. Haehl, R. Loganayagam, Mukund Rangamani
We focus on the question of how relativistic fluid dynamics should be thought of as a Wilsonian effective field theory emerging from Schwinger-Keldysh path integrals. Taking the ba…
Comments on universal properties of entanglement entropy and bulk reconstruction
Felix M. Haehl
Entanglement entropy of holographic CFTs is expected to play a crucial role in the reconstruction of semiclassical bulk gravity. We consider the entanglement entropy of spherical r…
Adiabatic hydrodynamics: The eightfold way to dissipation
Felix M. Haehl, R. Loganayagam, Mukund Rangamani
We provide a complete solution to hydrodynamic transport at all orders in the gradient expansion compatible with the second law constraint. The key new ingredient we introduce is t…
