Diffusive transport in spin-1 chains at high temperatures
J. Karadamoglou, X. Zotos
We present a numerical study on the spin and thermal conductivities of the spin-1 Heisenberg chain in the high temperature limit, in particular of the Drude weight contribution and…

Finite Temperature Dynamical Correlations using the Microcanonical Ensemble and the Lanczos Algorithm
M. W. Long, P. Prelovsek, S. El Shawish +2
We show how to generalise the zero temperature Lanczos method for calculating dynamical correlation functions to finite temperatures. The key is the microcanonical ensemble, which…
