The fate of orbitons coupled to phonons
K. P. Schmidt, M. Grüninger, G. S. Uhrig
The key feature of an orbital wave or orbiton is a significant dispersion, which arises from exchange interactions between orbitals on distinct sites. We study the effect of a coup…

Orbital excitations in titanates
C. Ulrich, A. Gössling, M. Grüninger +6
Raman scattering is used to observe pronounced electronic excitations around 230 meV - well above the two-phonon range - in the Mott insulators LaTiO and YTiO. Based on the…

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 $…
