Generalised global symmetries in states with dynamical defects: the case of the transverse sound in field theory and holography
Sašo Grozdanov, Napat Poovuttikul
In this work, we show how states with conserved numbers of dynamical defects (strings, domain walls, etc.) can be understood as possessing generalised global symmetries even when t…
Weak Quantum Chaos
Ivan Kukuljan, Sašo Grozdanov, Tomaž Prosen
Out-of-time-ordered correlation functions (OTOC's) are presently being extensively debated as quantifiers of dynamical chaos in interacting quantum many-body systems. We argue that…
Generalized global symmetries and dissipative magnetohydrodynamics
Sašo Grozdanov, Diego M. Hofman, Nabil Iqbal
The conserved magnetic flux of U(1) electrodynamics coupled to matter in four dimensions is associated with a generalized global symmetry. We study the realization of such a symmet…
Universality of anomalous conductivities in theories with higher-derivative holographic duals
Sašo Grozdanov, Napat Poovuttikul
Anomalous chiral conductivities in theories with global anomalies are independent of whether they are computed in a weakly coupled quantum (or thermal) field theory, hydrodynamics,…
Incoherent thermal transport from dirty black holes
Sašo Grozdanov, Andrew Lucas, Koenraad Schalm
We study thermal transport in strongly disordered, strongly interacting quantum field theories without quasiparticles using gauge-gravity duality. We analyze linear perturbations o…
Constructing higher-order hydrodynamics: The third order
Sašo Grozdanov, Nikolaos Kaplis
Hydrodynamics can be formulated as the gradient expansion of conserved currents in terms of the fundamental fields describing the near-equilibrium fluid flow. In the relativistic c…
Dynamics of the electric current in an ideal electron gas: a sound mode inside the quasi-particles
Sašo Grozdanov, Janos Polonyi
We study the equation of motion for the Noether current in an electron gas within the framework of the Schwinger-Keldysh Closed-Time-Path formalism. The equation is shown to be hig…
Viscosity and dissipative hydrodynamics from effective field theory
Sašo Grozdanov, Janos Polonyi
With the goal of deriving dissipative hydrodynamics from an action, we study classical actions for open systems, which follow from the generic structure of effective actions in the…
