Robust spin-polarized midgap states at step edges of topological crystalline insulators
Paolo Sessi, Domenico Di Sante, Andrzej Szczerbakow +11
Topological crystalline insulators are materials in which the crystalline symmetry leads to topologically protected surface states with a chiral spin texture, rendering them potent…
Single electron gating of topological insulators
Paolo Sessi, Thomas Bathon, Konstantin A. Kokh +2
Introducing, observing, and manipulating individual impurities coupled to a host material offers the opportunity to create new device concepts based on single spin and charge state…
Mapping the effect of defect-induced strain disorder on the Dirac states of topological insulators
Oliver Storz, Alberto Cortijo, Stefan Wilfert +6
We provide a detailed microscopic characterization of the influence of defects-induced disorder onto the Dirac spectrum of three dimensional topological insulators. By spatially re…
Impurity screening and stability of Fermi arcs against Coulomband magnetic scattering in a Weyl monopnictide
Paolo Sessi, Yan Sun, Thomas Bathon +9
We present a quasiparticle interference study of clean and Mn surface-doped TaAs, a prototypical Weyl semimetal, to test the screening properties as well as the stability of Fermi…
Coexistence of charge and ferromagnetic order in fcc Fe
Pin-Jui Hsu, Jens Kuegel, Jeannette Kemmer +5
Phase coexistence phenomena have been intensively studied in strongly correlated materials where several ordered states simultaneously occur or compete. Material properties critica…
Mesoscopic electron focusing in topological insulators
P. Sessi, P. Rüßmann, T. Bathon +15
The particle wave duality sets a fundamental correspondence between optics and quantum mechanics. Within this framework, the propagation of quasiparticles can give rise to superpos…
