This review summarizes recent advances in our understanding of anomalous transport in spin chains, viewed through the lens of integrability. Numerical advances, based on tensor …
Transport properties provide important access to a solid's quasiparticles, such as quasiparticle density, mobility, and scattering. The transport of heat can be particularly …
We study the spin and energy dynamics in one-dimensional spin-1 2 systems induced by local quantum quenches at finite temperatures using a time-dependent density matrix …

Using the adaptive time-dependent density matrix renormalization group method, we numerically study the spin dynamics and transport in one-dimensional spin-1/2 systems at …

We investigate the role of momentum for the transport of magnetization in the spin-1/2 Heisenberg chain above the isotropic point at finite temperature and momentum. Using …
We study the spin and thermal conductivity of spin-1 2 ladders and chains at finite temperature, relevant for experiments with quantum magnets. Using a state-of-the-art …
We study the real-time dynamics of the local energy density in the spin-1/2 XXZ chain starting from initial states with an inhomogeneous profile of bond energies. Numerical …
Integrable models such as the spin-1/2 Heisenberg chain, the Lieb-Liniger, or the one- dimensional Hubbard model are known to avoid thermalization, which was also …
Thirty-five years ago, Sanders and Walton [Phys. Rev. B 15, 1489 (1977) PRBMDO 0163- 1829] proposed a method to measure the phonon-magnon interaction in antiferromagnets …
