Coherent spin-current oscillations in transverse magnetic fields
R. Steinigeweg, S. Langer, F. Heidrich-Meisner +2
We address the coherence of the dynamics of spin-currents with components transverse to an external magnetic field for the spin-1/2 Heisenberg chain. We study current autocorrelati…

A real-time study of diffusive and ballistic transport in spin-1/2 chains using the adaptive time-dependent density matrix renormalization group method
S. Langer, F. Heidrich-Meisner, J. Gemmer +2
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 zero temp…
