A bulk-boundary correspondence for dynamical phase transitions in one-dimensional topological insulators and superconductors
N. Sedlmayr, P. Jäger, M. Maiti +1
We study the Loschmidt echo for quenches in open one-dimensional lattice models with symmetry protected topological phases. For quenches where dynamical quantum phase transitions d…
Signature of a topological phase transition in long SN junctions in the spin-polarized density of states
M. Guigou, N. Sedlmayr, J. M. Aguiar-Hualde +1
We investigate the spin texture of Andreev bound states and Majorana states in long SN junctions. We show that measuring the spin-polarized density of states (SPDOS) allows one to…
Conducting fixed points for inhomogeneous quantum wires: a conformally invariant boundary theory
N. Sedlmayr, D. Morath, J. Sirker +2
Inhomogeneities and junctions in wires are natural sources of scattering, and hence resistance. A conducting fixed point usually requires an adiabatically smooth system. One notabl…
Dynamics of the polarization of a pinned domain wall in a magnetic nanowire
N. Sedlmayr, V. Dugaev, J. Berakdar
We consider the dynamics of polarization of a single domain wall in a magnetic nanowire, which is strongly pinned by impurities. In this case the equation of motion for the polariz…
Transport Properties of an Interacting Quantum Dot with a Non-Uniform Magnetization
N. Sedlmayr, J. Berakdar
We study the influence of the non-homogeneity of a magnetization field on the behaviour of interacting electrons in a quantum dot. In particular we investigate the magnetotransport…
