Finite-temperature transport in one-dimensional quantum lattice models
Overview
Paper Summary
This review examines how heat and spin flow in 1D quantum systems, especially those with special mathematical properties (integrable models) like the Heisenberg and Hubbard models. It covers recent theoretical and computational advances like Generalized Hydrodynamics, explaining how these systems can be surprisingly good conductors even when strongly interacting, sometimes displaying exotic phenomena like "superdiffusion."
Explain Like I'm Five
Scientists found that in very thin, tiny materials, heat and a kind of tiny magnetism can flow super fast, sometimes even better than expected, like a special highway for energy.

Rating Explanation
This is a comprehensive and well-written review that summarizes a significant amount of research on transport in 1D quantum lattice models. It clearly explains the theoretical background, key concepts, and various methods used to study transport properties, highlighting recent progress and open questions. The review primarily focuses on integrable systems, but also discusses non-integrable systems and their connection to real materials and experiments. While the review could benefit from a more detailed discussion of practical applications and experimental results, its strengths in clarity, comprehensiveness, and overall quality outweigh these limitations.
