Review

This research explores the complex transport properties of one-dimensional disordered spin systems, focusing on the spin-1/2 and spin-1 chains. The authors use a strong-disorder renormalization group (SDRG) approach to analyze the frequency-dependent spin conductivity, revealing a critical insight: the distribution of conductivity becomes increasingly broad at low frequencies. The key contribution lies in resolving an apparent contradiction between previous predictions of a metallic spin phase and the known localized behavior of these systems. By carefully examining the distribution of conductivity—rather than just its average value—the researchers show that the typical (geometric average) conductivity vanishes, indicating an insulating state, even though the arithmetic average suggests metallicity.

 Abstract

 We study the spin transport properties of some disordered spin chains with a special focus on the distribution of the frequency-dependent spin conductivity. In the cases of interest here, the systems are governed by an effectively infinite disorder at low energies. A hallmark of this behavior is the wide discrepancy between the average and the typical values of some physical quantities, which are described by extremely broad distributions. We show that such is also the case of the spin conductivity, whose average value is metallic but whose typical one, the physically relevant quantity, is insulating. This solves the apparent contradiction between the prediction of a spin metallic phase of the spin-1/2 disordered XX chain and its known localized behavior (after a mapping to free fermions). Our results are based on analytical and numerical implementations of a strong-disorder renormalization group as well as exact diagonalization studies. We present our analyses in very general terms, valid for systems of any spin S 𝑆 S value, but the cases of S = 1 / 2 𝑆 1 2 S=1/2 and 1 are studied in greater detail. 

 
 
 
 I Introduction 

 
 In one-dimensional spin systems, the interplay of quantum fluctuations and disorder leads to distinctive behavior  [ 1 , 2 , 3 ] . Broadly speaking, in a wide class of systems and regimes, the effective disorder grows without limit at increasingly lower energies and longer length scales.
This unique feature allows for unprecedented detail and precision in their theoretical description. For example, thermodynamic properties can be obtained exactly at low temperatures T 𝑇 T : the specific heat and the magnetic susceptibility behave as c V  ( T ) ∼ | ln ⁡ T | − ( 1 + 1 / ψ ) similar
