Breakdown of emergent Lifshitz symmetry in holographic matter with Harris-marginal disorder
arXiv:2004.06543 · doi:10.1007/JHEP06(2020)023
Abstract
We revisit the theory of strongly correlated quantum matter perturbed by Harris-marginal random-field disorder, using the simplest holographic model. We argue that for weak disorder, the ground state of the theory is not Lifshitz invariant with a non-trivial disorder-dependent dynamical exponent, as previously found. Instead, below a non-perturbatively small energy scale, we predict infrared physics becomes independent of the disorder strength.
