The parity effect in Josephson junction arrays
Jared H. Cole, Andreas Heimes, Timothy Duty +1
We study the parity effect and transport due to quasiparticles in circuits comprised of many superconducting islands. We develop a general approach and show that it is equivalent t…
Tunneling and Relaxation of Single Quasiparticles in a Normal-Superconductor-Normal Single Electron Transistor
Andreas Heimes, Ville F. Maisi, Dmitri S. Golubev +3
We investigate the properties of a hybrid single electron transistor, involving a small superconducting island sandwiched between normal metal leads, which is driven by dc plus ac…
Single quasiparticle excitation dynamics on a superconducting island
V. F. Maisi, S. V. Lotkhov, A. Kemppinen +3
We investigate single quasiparticle excitation dynamics on a small superconducting aluminum island connected to normal metallic leads by tunnel junctions. We find the island to be…
The effect of spin fluctuations on the electronic structure in iron based superconductors
Andreas Heimes, Roland Grein, Matthias Eschrig
Magnetic inelastic neutron scattering (INS) studies of iron-based superconductors reveal a strongly temperature-dependent spin-fluctuation spectrum in the normal conducting state,…
Electronic dispersion anomalies in the iron pnictide superconductor Ba_{1-x}K_xFe_2As_2
Andreas Heimes, Roland Grein, Matthias Eschrig
The pairing mechanism in the iron-pnictide superconductors is still unknown. However, similarities to the cuprate high-temperature superconductors suggest that a similar mechanism…
