Transport properties play a crucial role in defining materials as insulators, metals, or
superconductors. A fundamental parameter in this regard is the Drude weight, which …

Anomalous charge transport in the sine-Gordon model

F Møller, BC Nagy, M Kormos, G Takács - arXiv preprint arXiv:2411.11473, 2024 - arxiv.org
We conduct a comprehensive study of anomalous charge transport in the quantum sine--
Gordon model. Employing the framework of Generalized Hydrodynamics, we compute …
