Important properties of a particle, wave or a statistical system depend on the form of a
dispersion relation (DR). Two commonly-discussed dispersion relations are the gapless …

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 introduce new classes of hydrodynamic theories inspired by the recently discovered
fracton phases of quantum matter. Fracton phases are characterized by elementary …

We present the first generalization of Navier-Stokes theory to relativity that satisfies all of the
following properties:(a) the system coupled to Einstein's equations is causal and strongly …

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 …

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 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 Pole skip** is a recently discovered subtle effect in the thermal energy density
retarded two point function at a special point in the complex (ω, p) planes. We propose that …

Relativistic magnetohydrodynamics (RMHD) provides an extremely useful description of the
low-energy long-wavelength phenomena in a variety of physical systems from quark–gluon …

We develop a relativistic (quasi-) hydrodynamic framework, dubbed gyrohydrodynamics, to
describe the fluid dynamics of many-body systems with spin under strong vorticity based on …
