Spin-polarized (001) surface states of the topological crystalline insulator Pb_{0.73}Sn_{0.27}Se
B. M. Wojek, R. Buczko, S. Safaei +9
We study the nature of (001) surface states in Pb_{0.73}Sn_{0.27}Se in the newly discovered topological-crystalline-insulator (TCI) phase as well as the corresponding topologically…
The J_{eff}=1/2 insulator Sr3Ir2O7 studied by means of angle-resolved photoemission spectroscopy
B. M. Wojek, M. H. Berntsen, S. Boseggia +6
The low-energy electronic structure of the J_{eff}=1/2 spin-orbit insulator Sr3Ir2O7 has been studied by means of angle-resolved photoemission spectroscopy. A comparison of the res…
Direct observation of decoupled Dirac states at the interface between topological and normal insulators
M. H. Berntsen, O. Götberg, B. M. Wojek +1
Several proposed applications and exotic effects in topological insulators rely on the presence of helical Dirac states at the interface between a topological and a normal insulato…
Topological crystalline insulator states in Pb(1-x)Sn(x)Se
P. Dziawa, B. J. Kowalski, K. Dybko +9
Topological insulators are a novel class of quantum materials in which time-reversal symmetry, relativistic (spin-orbit) effects and an inverted band structure result in electronic…
The Meissner effect in a strongly underdoped cuprate above its critical temperature
Elvezio Morenzoni, Bastian M. Wojek, Andreas Suter +3
The Meissner effect and the associated perfect "bulk" diamagnetism together with zero resistance and gap opening are characteristic features of the superconducting state. In the ps…
Magnetism, superconductivity and coupling in cuprate heterostructures probed by low-energy muon-spin rotation
B. M. Wojek, E. Morenzoni, D. G. Eshchenko +8
We present a low-energy muon-spin-rotation study of the magnetic and superconducting properties of YBa2Cu3O7/PrBa2Cu3O7 trilayer and bilayer heterostructures. By determining the ma…
