Signatures of topological phase transitions in mesoscopic superconducting rings
Falko Pientka, Alessandro Romito, Mathias Duckheim +2
We investigate Josephson currents in mesoscopic rings with a weak link which are in or near a topological superconducting phase. As a paradigmatic example, we consider the Kitaev m…
Endstates in multichannel spinless p-wave superconducting wires
M. -T. Rieder, G. Kells, M. Duckheim +2
Multimode spinless p-wave superconducting wires with a width W much smaller than the superconducting coherence length ξare known to have multiple low-energy subgap states localized…
Probability distribution of Majorana end-state energies in disordered wires
Piet W. Brouwer, Mathias Duckheim, Alessandro Romito +1
One-dimensional topological superconductors harbor Majorana bound states at their ends. For superconducting wires of finite length L, these Majorana states combine into fermionic e…
Topological superconducting phases in disordered quantum wires with strong spin-orbit coupling
Piet W. Brouwer, Mathias Duckheim, Alessandro Romito +1
Zeeman fields can drive semiconductor quantum wires with strong spin-orbit coupling and in proximity to s-wave superconductors into a topological phase which supports end Majorana…
Andreev reflection from non-centrosymmetric superconductors and Majorana bound state generation in half-metallic ferromagnets
Mathias Duckheim, Piet W. Brouwer
We study Andreev reflection at an interface between a half metal and a superconductor with spin-orbit interaction. While the absence of minority carriers in the half metal makes si…
Geometric Correlations and Breakdown of Mesoscopic Universality in Spin Transport
I. Adagideli, Ph. Jacquod, M. Scheid +3
We construct a unified semiclassical theory of charge and spin transport in chaotic ballistic and disordered diffusive mesoscopic systems with spin-orbit interaction. Neglecting dy…
Spin Accumulation in Diffusive Conductors with Rashba and Dresselhaus Spin-Orbit Interaction
Mathias Duckheim, Daniel Loss, Matthias Scheid +3
We calculate the electrically induced spin accumulation in diffusive systems due to both Rashba (with strength and Dresselhaus (with strength spin-orbit interaction. Usin…
Dynamic spin-Hall effect and driven spin helix for linear spin-orbit interactions
Mathias Duckheim, Dmitrii L. Maslov, Daniel Loss
We derive boundary conditions for the electrically induced spin accumulation in a finite, disordered 2D semiconductor channel. While for DC electric fields these boundary condition…
Mesoscopic fluctuations in the spin-electric susceptibility due to Rashba spin-orbit interaction
Mathias Duckheim, Daniel Loss
We investigate mesoscopic fluctuations in the spin polarization generated by a static electric field and by Rashba spin-orbit interaction in a disordered 2D electron gas. In a diag…
Resonant spin polarization and spin current in a two-dimensional electron gas
Mathias Duckheim, Daniel Loss
We study the spin polarization and its associated spin-Hall current due to EDSR in disordered two-dimensional electron systems. We show that the disorder induced damping of the res…
Electric Dipole Induced Spin Resonance in Disordered Semiconductors
Mathias Duckheim, Daniel Loss
One of the hallmarks of spintronics is the control of magnetic moments by electric fields enabled by strong spin-orbit interaction (SOI) in semiconductors. A powerful way of manipu…
Influence of low-frequency noise on macroscopic quantum tunneling in superconducting circuits
M. Duckheim, J. Ankerhold
The influence of low to moderate frequency environments on Macroscopic Quantum Tunneling (MQT) in superconducting circuits is studied within the Im-F approach to evaluate tunneling…
