Flat Holography & Holographic Renormalization: Scalar Field
Martin Ammon, Federico Capone, Christoph Sieling
We adapt the Hamilton-Jacobi method of holographic renormalization to scalar field theories in Minkowski spacetime with scattering boundary conditions. The approach yields a flat-s…
A Holographic prescription for generalized Schwinger-Keldysh contours
Martin Ammon, Jette Germerodt, Christoph Sieling +1
We provide a holographic prescription to compute real-time thermal correlators with arbitrary operator ordering. In field theory, these correlation functions are captured by a mult…
Strongly interacting matter in extreme magnetic fields
Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58
Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…
Unfolded Fierz-Pauli Equations in Three-Dimensional Asymptotically Flat Spacetimes
Martin Ammon, Michel Pannier
We utilise a quotient of the universal enveloping algebra of the Poincaré algebra in three spacetime dimensions, on which we formulate a covariant constancy condition. The equation…
Pseudo-spontaneous Symmetry Breaking in Hydrodynamics and Holography
Martin Ammon, Daniel Arean, Matteo Baggioli +2
We investigate the low-energy dynamics of systems with pseudo-spontaneously broken symmetry and Goldstone phase relaxation. We construct a hydrodynamic framework which is ab…
Chiral hydrodynamics in strong external magnetic fields
Martin Ammon, Sebastian Grieninger, Juan Hernandez +4
We construct the general hydrodynamic description of (3+1)-dimensional chiral charged (quantum) fluids subject to a strong external magnetic field with effective field theory metho…
