Nodal superconductivity with spin-triplet component in a noncentrosymmetric weakly-correlated metal
Marcel Strohmeier, Andriy Smolyanyuk, Karsten Held +5
Although Cooper pairs in superconductors generally condense into a spin-singlet state, spin-triplet superconductivity has attracted sustained interest for dissipationless spin tran…
Nonmonotonic temperature dependence of the thermopower of atomic-size gold contacts
Thomas B. Möller, Marcel Strohmeier, Johannes Boneberg +3
We report measurements of the thermopower of atomic-size gold contacts realized by the mechanically controllable break junction (MCBJ) technique over a temperature range from 18 K…
Spin-polarized transport in copper-oxide atomic junctions revealed by anomalous shot-noise behavior in presence of the Kondo effect
Marcel Strohmeier, Samanwita Biswas, Wolfgang Belzig +2
Noise measurements provide a valuable tool for revealing spin polarization effects in the electronic transport through quantum coherent conductors. We present an extension of the L…
Testing time order and Leggett-Garg inequalities with noninvasive measurements on public quantum computers
Tomasz Rybotycki, Tomasz BiaÅecki, Josep Batle +4
We demonstrate the first violation of the Leggett-Garg inequality and time-order noninvariance on public quantum computers using genuine noninvasive measurements. By gathering suff…
Full Counting Statistics of Yu-Shiba-Rusinov Bound States
David Christian Ohnmacht, Wolfgang Belzig, Juan Carlos Cuevas
With the help of scanning tunneling microscopy (STM) it has become possible to address single magnetic impurities on superconducting surfaces and to investigate the peculiar proper…
