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

Holographic fermions at strong translational symmetry breaking: a Bianchi-VII case study
TL;DR: In this paper, the Bianchi-VII geometry has been studied in the regime where holographic quasi-particles occur, defining a Fermi surface in the continuum, and they acquire a finite lifetime at any finite potential strength.

On Effective Holographic Mott Insulators
Matteo Baggioli,Oriol Pujolàs +1 more
TL;DR: In this paper, a class of holographic models that behave effectively as prototypes of Mott insulators, materials where electron-electron interactions dominate transport phenomena, are presented, which imply a clear and generic correlation between Mott behaviour and significant effects in the nonlinear electrical response.

Hyperscaling violating solutions in generalised EMD theory
TL;DR: In this article, the authors derive scaling but hyperscaling violating solutions in a generalised Einstein-Maxwell-Dilaton theory with an arbitrary number of scalars and vectors, and discuss the physical constraints on the allowed parameter range in order to have a well-defined holographic ground state solution.

Commensurability effects in holographic homogeneous lattices
TL;DR: In this article, the authors investigate the phenomenon of commensurability, which arises when the lattice scale is tuned to be equal to (an integer multiple of) another momentum scale in the system.

Boomerang RG flows with intermediate conformal invariance.
TL;DR: For a class of D = 5 holographic models, this article constructed boomerang RG flow solutions that start in the UV at an AdS5 vacuum and end up at the same vacuum in the IR.
