Over the last decade impressive progress has been made in the theoretical understanding
of transport properties of clean, one-dimensional quantum lattice systems. Many physically …

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 how perturbations affect dynamics of integrable many-body quantum systems,
causing transition from integrability to chaos. Looking at spin transport in the Heisenberg …

We review recent theoretical and experimental efforts aimed at the investigation of the
physics of interacting disordered bosons (so-called dirty bosons) in the context of quantum …

We studied transport properties of a disordered tight-binding model (XX spin chain) in the
presence of dephasing. Focusing on diffusive behaviour in the thermodynamic limit at high …

We study the breaking of integrability by a finite density of dilute impurities, specifically the
emerging diffusive transport. Provided the distance between impurities (localized …

We have investigated the thermal conductivity κ mag of high-purity single crystals of the spin
chain compound Sr 2 CuO 3, which is considered an excellent realization of the one …

The spin ladder compound (Sr, Ca, La) 14Cu24O41 exhibits an incommensurate layered
structure with strong antiferromagnetic coupling. Besides intriguing superconducting …

The heat transport in a system of S= 1/2 large-J Heisenberg spin chains, describing closely
Sr 2 CuO 3 and SrCuO 2 cuprates, is studied theoretically at T≪ J by considering …

The thermal conductance of a one-dimensional classical inertial Heisenberg model of linear
size L is computed, considering the first and last particles in thermal contact with heat baths …
