Bond disorder and spinon heat transport in the Heisenberg spin chain compound SrCuO: from clean to dirty limits
A. Mohan, N. Sekhar Beesetty, N. Hlubek +4
We investigate the effect of disorder on the heat transport properties of the Heisenberg chain compound SrCuO upon chemically substituting Sr by increasing…
Spinon heat transport and spin-phonon interaction in the antiferromagnetic spin-1/2 Heisenberg chain cuprates Sr2CuO3 and SrCuO2
N. Hlubek, X. Zotos, S. Singh +4
We have investigated the thermal conductivity κ_mag of high-purity single crystals of the spin chain compound Sr2CuO3 which is considered an excellent realization of the one-dimens…
Bond disorder and breakdown of ballistic heat transport in the spin-1/2 antiferromagnetic Heisenberg chain as seen in Ca-doped SrCuO2
N. Hlubek, P. Ribeiro, R. Saint-Martin +9
We study the impact of a weak bond disorder on the spinon heat transport in the S=1/2 antiferromagnetic (AFM) Heisenberg chain material Sr_{1-x}Ca_xCuO_2. We observe a drastic supp…
Heat conductivity of the spin-Peierls compounds TiOCl and TiOBr
N. Hlubek, M. Sing, S. Glawion +5
We report experimental results on the heat conductivity κof the S=1/2 spin chain compounds TiOBr and TiOCl for temperatures 5K<T<300K and magnetic fields up to 14. Surprisingly, we…
Ballistic heat transport of quantum spin excitations as seen in SrCuO2
N. Hlubek, P. Ribeiro, R. Saint-Martin +5
Fundamental conservation laws predict ballistic, i.e., dissipationless transport behaviour in one-dimensional quantum magnets. Experimental evidence, however, for such anomalous tr…
