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 study charge diffusion in holographic scaling theories with a particle-hole symmetry. We
show that these theories have a universal regime in which the diffusion constant is given by …

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 …

We present a holographic perspective on momentum transport in strongly coupled,
anisotropic non-Abelian plasmas in the presence of strong magnetic fields. We compute the …

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 Momentum dissipation is an important ingredient in condensed matter physics that
requires a translation breaking sector. In the bottom-up gauge/gravity duality, this implies …

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 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 …

A bstract The ratio of shear viscosity to entropy density, η/s, is computed in various
holographic geometries that break translation invariance (but are isotropic). The shear …
