Titre |
Holographic Schwinger-Keldysh effective field theories |
|
Résumé |
Hydrodynamics has been recently reformulated as an effective field theory based on an
underlying Schwinger-Keldysh path integral. After a pedagogical introduction to the
formalism, I will show how effective actions of this type can be derived from holography using
a mixed signature bulk spacetime whereby an eternal asymptotically anti-de Sitter black hole
is glued to its Euclidean counterpart along an initial time slice in a way to match the desired
double-time contour of the dual field theory. For concreteness, I will consider the example of
dissipative low-energy dynamics of relativistic charged matter at strong coupling in a fixed
thermal background. |
