What is Electronic structure and fluctuation effects in the spin-1/2 quantum magnet TiOCl about?
We present a joint experimental and theoretical study of the spin-1/2 quantum magnet TiOCl. From polarization-dependent momentum-resolved photoemission spectroscopy we can exclude sizable phononinduced orbital fluctuations as origin for the non-canonical phenomenology of the spin-Peierls transition in this compound. While our data does confirm the quasi-one-dimensional character of the electronic structure along the crystallographic b-axis as inferred from previous LDA+U calculations these as well as other band and model calculations apparently fail to describe the detailed behavior of the quasi-one-dimensional dispersions in the normal state of this material.
