U(1) quasi-hydrodynamics: Schwinger-Keldysh effective field theory and holography
Matteo Baggioli, Yanyan Bu, Vaios Ziogas
We study the quasi-hydrodynamics of a system with a softly broken global symmetry using effective field theory (EFT) and holographic methods. In the gravity side, we conside…
Damping of Pseudo-Goldstone Fields
Luca V. Delacrétaz, Blaise Goutéraux, Vaios Ziogas
Approximate symmetries abound in Nature. If these symmetries are also spontaneously broken, the would-be Goldstone modes acquire a small mass, or inverse correlation length, and ar…
Incoherent hydrodynamics of density waves in magnetic fields
Aristomenis Donos, Christiana Pantelidou, Vaios Ziogas
We use holography to derive effective theories of fluctuations in spontaneously broken phases of systems with finite temperature, chemical potential, magnetic field and momentum re…
Phase diagram of a two-site coupled complex Sachdev-Ye-Kitaev model
Antonio M. García-García, Jie Ping Zheng, Vaios Ziogas
We study the thermodynamic properties of a two-site coupled complex Sachdev-Ye-Kitaev (SYK) model in the large limit by solving the saddle-point Schwinger-Dyson (SD) equations.…
Incoherent hydrodynamics and density waves
Aristomenis Donos, Daniel Martin, Christiana Pantelidou +1
We consider thermal phases of holographic lattices at finite chemical potential in which a continuous internal bulk symmetry can be spontaneously broken. In the normal phase, trans…
Hydrodynamics of broken global symmetries in the bulk
Aristomenis Donos, Daniel Martin, Christiana Pantelidou +1
We consider holographic theories at finite temperature in which a continuous global symmetry in the bulk is spontaneously broken. We study the linear response of operators in a reg…
Incoherent transport for phases that spontaneously break translations
Aristomenis Donos, Jerome P. Gauntlett, Tom Griffin +1
We consider phases of matter at finite charge density which spontaneously break spatial translations. Without taking a hydrodynamic limit we identify a boost invariant incoherent c…
Diffusion for Holographic Lattices
Aristomenis Donos, Jerome P. Gauntlett, Vaios Ziogas
We consider black hole spacetimes that are holographically dual to strongly coupled field theories in which spatial translations are broken explicitly. We discuss how the quasinorm…
Diffusion in inhomogeneous media
Aristomenis Donos, Jerome P. Gauntlett, Vaios Ziogas
We consider the transport of conserved charges in spatially inhomogeneous quantum systems with a discrete lattice symmetry. We analyse the retarded two point functions involving th…
Holographic mutual information in global Vaidya-BTZ spacetime
Vaios Ziogas
We investigate the evolution of the mutual information between two spatial subsystems in a compact 1+1 dimensional CFT after a quantum quench. To this end, we use the dual holograp…
