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 …

Plasmonics represents a unique approach to confine and enhance electromagnetic
radiation well below the diffraction limit, bringing a huge potential for novel applications, for …

In a recent work [J. Lenz, Phys. Rev. D 101, 094512 (2020) PRVDAQ 2470-0010
10.1103/PhysRevD. 101.094512] we studied the phase structure of the Gross-Neveu (GN) …

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 …

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 …

A bstract We conduct an exhaustive study of the interior geometry of a family of
asymptotically AdS d+ 1 hairy black holes in an analytically controllable setup. The black …

A bstract We construct the general hydrodynamic description of (3+ 1)-dimensional chiral
charged (quantum) fluids subject to a strong external magnetic field with effective field theory …

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 …

We propose a general hydrodynamic framework for systems with spontaneously broken
approximate symmetries. The second law of thermodynamics naturally results in relaxation …

A bstract Pseudo-Goldstone modes appear in many physical systems and display robust
universal features. First, their mass m obeys the so-called Gell-Mann-Oakes-Renner …
