Interaction-driven localization in holography
TLDR
In this paper, a periodic lattice was introduced to a holographic model developed by string theorists to study anisotropic materials that are insulating in certain directions but conducting in others.Abstract:
Strongly interacting condensed-matter systems are often computationally intractable. By introducing a periodic lattice to a holographic model developed by string theorists, it becomes possible to study anisotropic materials that are insulating in certain directions but conducting in others.read more

Phase transitions of an anisotropic N=4 super Yang-Mills plasma via holography
TL;DR: In this article, it was shown that the previously constructed black holes become unstable at low temperatures, and construct new classes of exotic black hole solutions that are thermodynamically preferred in the zero temperature limit.

Unitarity bound violation in holography and the Instability toward the Charge Density Wave
TL;DR: In this article, the authors studied the spectral function of fermions in a holographic set up with bulk Dirac mass in the regime beyond the conformal unitarity bound, and found that spectral function has the dispersion relation with tachyonic behavior, indicating an instability.

Anisotropic destruction of the Fermi surface in inhomogeneous holographic lattices
TL;DR: In this article, the authors analyze the fermionic response of strongly correlated holographic matter in presence of inhomogeneous periodically modulated potential mimicking the crystal lattice and show that it either exhibits a well defined Fermi surface with umklapp gaps opening on the Brillouin zone boundary at small lattice wave vector, or, when the wave vector is large, the Fermion surface is anisotropically deformed and quasiparticles get significantly broadened in the direction of translation symmetry breaking.
