Persistent current and Wigner crystallization in a one dimensional quantum ring
Marc Siegmund, Markus Hofmann, Oleg Pankratov
We use Density Functional Theory to study interacting spinless electrons on a one-dimensional quantum ring in the density range where the system undergoes Wigner crystallization. T…
Evidence for a large magnetic heat current in insulating cuprates
M. Hofmann, T. Lorenz, K. Berggold +4
The in-plane thermal conductivity of the two-dimensional antiferromagnetic monolayer cuprate SrCuOCl is studied. Analysis of the unusual temperature dependence of $…
Heat transport in SrCu_2(BO_3)_2 and CuGeO_3
M. Hofmann, T. Lorenz, A. Freimuth +5
In the low dimensional spin systems and the thermal conductivities along different crystal directions show pronounced double-peak structures and strongly…
Strong damping of phononic heat current by magnetic excitations in SrCu_2(BO_3)_2
M. Hofmann, T. Lorenz, G. S. Uhrig +5
Measurements of the thermal conductivity as a function of temperature and magnetic field in the 2D dimer spin system SrCu(BO) are presented. In zero magnetic field the…
