Direct Optical Coupling to an Unoccupied Dirac Surface State in the Topological Insulator BiSe
Jonathan A. Sobota, Shuolong Yang, Alexander F. Kemper +9
We characterize the occupied and unoccupied electronic structure of the topological insulator BiSe by one-photon and two-photon angle-resolved photoemission spectroscopy an…
Spectroscopic evidence for polaronic behaviour of the strong spin-orbit insulator SrIrO
P. D. C. King, T. Takayama, A. Tamai +9
We investigate the bilayer Ruddlesden-Popper iridate SrIrO by temperature-dependent angle-resolved photoemission. We find a narrow-gap correlated insulator, with spectr…
Measurement of Coherent Polarons in the Strongly Coupled Antiferromagnetically Ordered Iron-Chalcogenide Fe1.02Te using Angle-Resolved Photoemission Spectroscopy
Zhongkai Liu, Ruihua He, Donghui Lu +12
The nature of metallicity and the level of electronic correlations in the antiferromagnetically ordered parent compounds are two important open issues for the iron-based supercondu…
Superconductivity distorted by the coexisting pseudogap in the antinodal region of BiPbSrLaCuO: A photon-energy-dependent angle-resolved photoemission study
M. Hashimoto, R. -H. He, I. M. Vishik +8
The interplay between superconductivity and the pseudogap is an important aspect of cuprate physics. However, the nature of the pseudogap remains controversial, in part because dif…
Intrinsic Ultrathin Topological Insulators Grown via MBE Characterized by in-situ Angle Resolved Photoemission Spectroscopy
J. J. Lee, F. T. Schmitt, R. G. Moore +3
We demonstrate the capability of growing high quality ultrathin films of the topological insulators Bi2Se3 and Bi2Te3 using molecular beam epitaxy. Unlike previous growth technique…
Femtosecond dynamics of the collinear-to-spiral antiferromagnetic phase transition in CuO
S. L. Johnson, R. A. de Souza, U. Staub +22
We report on the ultrafast dynamics of magnetic order in a single crystal of CuO at a temperature of 207 K in response to strong optical excitation using femtosecond resonant x-ray…
