Lattice dynamics of endotaxial silicide nanowires
J. Kalt, M. Sternik, B. Krause +17
Self-organized silicide nanowires are considered as main building blocks of future nanoelectronics and have been intensively investigated. In nanostructures, the lattice vibrationa…
Electronic properties of BiSe dopped by transition metal (Mn, Fe, Co, or Ni) ions
Andrzej Ptok, Konrad Jerzy Kapcia, Anna Ciechan
Topological insulators are characterized by the existence of band inversion and the possibility of the realization of surface states. Doping with a magnetic atom, which is a source…
Probing the chirality of 1D Majorana edge states around a 2D nanoflake in a superconductor
Andrzej Ptok, David J. Alspaugh, Szczepan Głodzik +4
The interplay between superconductivity, magnetic field and spin-orbit coupling can lead to the realization of non--trivial topological phases. Recent experiments have found signat…
Majorana bound states in a superconducting Rashba nanowire in the presence of antiferromagnetic order
Aksel Kobiałka, Nicholas Sedlmayr, Andrzej Ptok
Theoretical studies have shown that Majorana bound states can be induced at the ends of a one dimensional wire, a phenomenon possible due to the interplay between s-wave supercondu…
Origin of monoclinic distortion and its impact on the electronic properties in KO
Olga Sikora, Dorota Gotfryd, Andrzej Ptok +4
We use the density functional theory and lattice dynamics calculations to investigate the properties of potassium superoxide KO in which spin, orbital, and lattice degrees of f…
Identification of the Majorana edge modes in tight-binding systems based on the Krylov method
Andrzej Więckowski, Andrzej Ptok, Marcin Mierzejewski +1
Low dimensional structures in the non-trivial topological phase can host the in-gap Majorana bound states, identified experimentally as zero-bias peaks in differential conductance.…
