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

A simple holographic model of momentum relaxation
Tomas Andrade,Benjamin Withers +1 more
TL;DR: In this paper, a holographic model consisting of Einstein-Maxwell theory in d + 1 bulk spacetime dimensions with d 1 massless scalarelds was considered, and the DC conductivity was analytically calculated.

Holographic Quantum Matter
TL;DR: In this paper, a review of theories of states of quantum matter without quasiparticle excitations is provided through a holographic duality with gravitational theories in an emergent spatial dimension.
Journal ArticleDOI
Holographic Q-lattices
TL;DR: In this article, the authors introduce a new framework for constructing black hole solutions that are holographically dual to strongly coupled field theories with explicitly broken translation invariance, which leads to constructions that involve solving ODEs instead of PDEs.
Journal ArticleDOI
Thermoelectric DC conductivities from black hole horizons
TL;DR: In this paper, an analytic expression for the DC electrical conductivity in terms of black hole horizon data was obtained for a class of holographic Q-lattices exhibiting momentum dissipation.

Charge transport in holography with momentum dissipation
TL;DR: In this paper, the authors examine how charge is transported in a theory where momentum is relaxed by spatially dependent, massless scalars, and analyze the possible IR phases in terms of various scaling exponents and the importance of operators in the IR effective holographic theory with a dilaton.

Universal linear in temperature resistivity from black hole superradiance
TL;DR: In this article, it is shown that at a holographic BKT critical point, if the unstable operator is coupled to the current via irrelevant operators, then a linear contribution to the resistivity is universally obtained.

The Pauli exclusion principle at strong coupling: holographic matter and momentum space
TL;DR: In this article, the authors investigated the effect of the Pauli exclusion principle on the spectral weight of strongly interacting quantum matter with a holographic dual and obtained the low energy current-current spectral weight in two holographic frameworks at finite density.

TL;DR: A direct measurement of the low-frequency optical conductivity of large-area single-crystal herbertsmithite, a promising spin-liquid candidate material, by means of terahertz time-domain spectroscopy, consistent with the theoretically predicted low- frequency conductivity arising from an emergent gauge field of a gapless U(1) Dirac spin liquid.

The Pauli exclusion principle at strong coupling: Holographic matter and momentum space
TL;DR: In this paper, the authors investigated the effect of the Pauli exclusion principle on the low energy spectral weight in strongly interacting quantum matter with a holographic dual and obtained the spectral weight as a function of momentum.

Power-law dependence of the optical conductivity observed in the quantum spin-liquid compound κ-(BEDT-TTF) 2 Cu 2 (CN) 3
TL;DR: Ng et al. as discussed by the authors observed a large in-gap absorption where the excess conductivity exhibits a power-law behavior that grows stronger as the temperature decreases and extends all the way through the far infrared, and suggested fluctuations become important in the spin-liquid state and couple to the electrodynamic properties differently compared to the antiferromagnetic Mott insulator.
