Two-dimensional ferromagnetic extension of a topological insulator
P. Kagerer, C. I. Fornari, S. Buchberger +19
Inducing a magnetic gap at the Dirac point of the topological surface state (TSS) in a 3D topological insulator (TI) is a route to dissipationless charge and spin currents. Ideally…
Kondo quasiparticle dynamics observed by resonant inelastic x-ray scattering
M. C. Rahn, K. Kummer, A. Hariki +18
Effective models focused on pertinent low-energy degrees of freedom have substantially contributed to our qualitative understanding of quantum materials. An iconic example, the Kon…
Is there a polaron signature in angle-resolved photoemission of CsPbBr3?
Maryam Sajedi, Maxim Krivenkov, Dmitry Marchenko +7
The formation of large polarons has been proposed as reason for the high defect tolerance, low mobility, low charge carrier trapping and low nonradiative recombination rates of lea…
