The consequences of electron-electron interactions are difficult to calculate reliably but this is needed to understand important physical properties such as ferromagnetism. Tusche et al. show that interaction effects in cobalt are nonlocal, presenti

The detailed electronic structure of a layered semiconductor 1T-TiS _2 and its modification in Ni-intercalated Ni _1/3 TiS _2 were studied beyond the full surface Brillouin zone by use of a momentum microscope and He-I light source on their in-situ c

2D oxide quasicrystals (OQCs) are recently discovered aperiodic, but well-ordered oxide interfaces. In this topical review, an introduction to these new thin-film systems is given. The concept of quasicrystals and their approximants is explained for

The valence band electronic structure of a BaTiO3-derived oxide quasicrystal (OQC) is studied by photoemission using momentum microscopy. An upward-dispersive O2p band is identified, and it can be assigned to a combination of in-plane orbitals accord

We report the in situ preparation of surfaces of the proposed topological Kondo insulator SmB by controlled cycles of Ar ion sputtering and annealing. The procedure provides a reproducible way for the preparation of Sm- or B-rich surface terminations
