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 …

A large and mostly unexplored part of the phase diagram lies above the critical point. The
supercritical matter was traditionally believed to be physically homogeneous with no …

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 …

We point out that there is an upper bound on the speed of sound squared given by cs 2≤
0.781 valid for all known systems described by relativistic transient hydrodynamics where …

Dusty plasmas represent a powerful platform to study the collective dynamics of strongly
coupled systems with important interdisciplinary connections to condensed matter physics …

A bstract Within the framework of holography, the Einstein-Maxwell action with Dirichlet
boundary conditions corresponds to a dual conformal field theory in presence of an external …

A bstract The holographic superconductor is one of the most popular models in the context
of applied holography. Despite what its name suggests, it does not describe a …

A bstract We investigate the low-energy dynamics of systems with pseudo-spontaneously
broken U (1) symmetry and Goldstone phase relaxation. We construct a hydrodynamic …

A bstract We investigate the properties of pole-skip** of the sound channel in which the
translational symmetry is broken explicitly or spontaneously. For this purpose, we analyze, in …

We propose superluminal solitons residing in the momentum gap (k gap) of nonlinear
photonic time crystals. These gap solitons are structured as plane waves in space while …
