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 …

The vibrational spectra of solids, both ordered and amorphous, in the low-energy regime,
control the thermal and transport properties of materials, from heat capacity to heat …

Motivated by high interest in Lorentz invariant massive gravity models known as dRGT
massive gravity, we present an exact phantom black hole solution in this theory of gravity …

We present a class of holographic massive gravity models that realize a spontaneous
breaking of translational symmetry—they exhibit transverse phonon modes whose speed …

A bstract We employ a deep learning method to deduce the bulk spacetime from boundary
optical conductivity. We apply the neural ordinary differential equation technique, tailored for …

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 …

SpringerBriefs in Physics are a series of slim high-quality publications encompassing the
entire spectrum of physics. Manuscripts for SpringerBriefs in Physics will be evaluated by …

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 study the pole-skip** phenomenon within holographic axion theories, a
common framework for studying strongly coupled systems with chemical potential (μ) and …
