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…
Semi-classical BMS-blocks from the Oscillator Construction
Martin Ammon, Seán Gray, Claire Moran +2
Flat-space holography requires a thorough understanding of BMS symmetry. We introduce an oscillator construction of the highest-weight representation of the alge…
On the Hydrodynamic Description of Holographic Viscoelastic Models
Martin Ammon, Matteo Baggioli, Seán Gray +2
We show that the correct dual hydrodynamic description of homogeneous holographic models with spontaneously broken translations must include the so-called "strain pressure" -- a no…
Longitudinal Sound and Diffusion in Holographic Massive Gravity
Martin Ammon, Matteo Baggioli, Seán Gray +1
We consider a simple class of holographic massive gravity models for which the dual field theories break translational invariance spontaneously. We study, in detail, the longitudin…
