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 …

Growing technical demand for thermal management stems from the pursuit of high–efficient
energy utilization and the reuse of wasted thermal energy, which necessitates the …

The honeycomb Kitaev-Heisenberg model is a source of a quantum spin liquid with
Majorana fermions and gauge flux excitations as fractional quasiparticles. Here we unveil …

Nonergodic dynamical systems display anomalous transport properties. Prominent
examples are integrable quantum systems, whose exceptional properties are diverging dc …

We analytically and numerically study spin transport in a one-dimensional Heisenberg
model in linear-response regime at infinite temperature. It is shown that as the anisotropy …

We demonstrate that the exact nonequilibrium steady state of the one-dimensional
Heisenberg XXZ spin chain driven by boundary Lindblad operators can be constructed …

We study the onset of chaos and statistical relaxation in two isolated dynamical quantum
systems of interacting spins 1/2, one of which is integrable and the other chaotic. Our …

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 …

We demonstrate that the concept of quantum typicality allows for significant progress in the
study of real-time spin dynamics and transport in quantum magnets. To this end, we present …

The honeycomb Kitaev model in a magnetic field is a source of a topological quantum spin
liquid with Majorana fermions and gauge flux excitations as fractional quasiparticles. We …
