Quantum criticality in the SO(5) bilinear-biquadratic Heisenberg chain
F. Alet, S. Capponi, H. Nonne +2
The zero-temperature properties of the SO(5) bilinear-biquadratic Heisenberg spin chain are investigated by means of a low-energy approach and large scale numerical calculations. I…

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…
