This is a complete and exhaustive review on the so-called holographic axion model—a
bottom-up holographic system characterized by the presence of a set of shift symmetric …

We review constructions of three-dimensional 'quantum'black holes. Such spacetimes arise
via holographic braneworlds and are exact solutions to an induced higher-derivative theory …

A bstract We show that holographic thermal two-sided two-point correlators take the form of
a product over quasi-normal modes (QNMs). Due to this fact, the two-point function admits a …

A bstract Quasinormal modes and frequencies are the eigenvectors and eigenvalues of a
non-Hermitian differential operator. They hold crucial significance in the physics of black …

We present an exact formula for the thermal scalar two-point function in four-dimensional
holographic conformal field theories. The problem of finding it reduces to the analysis of the …

A bstract We study analytic properties of the dispersion relations in classical hydrody-namics
by treating them as Puiseux series in complex momentum. The radii of convergence of the …

Hydrodynamics is a theory of long-range excitations controlled by equations of motion that
encode the conservation of a set of currents (energy, momentum, charge, etc.) associated …

A bstract The relaxation time approximation (RTA) of the kinetic Boltzmann equation is likely
the simplest window into the microscopic properties of collective real-time transport. Within …

A bstract We develop a method to study coupled dynamics of gauge-invariant variables,
constructed out of metric and gauge field fluctuations on the background of a AdS 5 …

A bstract We explore a new class of general properties of thermal holographic Green's
functions that can be deduced from the near-horizon behaviour of classical perturbations in …
