Thermally-induced crossover from 2D to 1D behavior in an array of atomic wires: silicon dangling-bond solitons in Si(553)-Au
B. Hafke, C. Brand, T. Witte +3
The self-assembly of submonolayer amounts of Au on the densely stepped Si(553) surface creates an array of closely spaced \atomic wires" separated by 1.5 nm. At low temperature, ch…
Relaxation dynamics in double-spin systems
Philipp Stegmann, Jürgen König, Björn Sothmann
We consider the relaxation dynamics of two spins coupled to a common bosonic bath. The time evolution is simulated by a generalized master equation derived within a real-time diagr…
On-demand thermoelectric generation of equal-spin Cooper pairs
Felix Keidel, Sun-Yong Hwang, Björn Trauzettel +2
Superconducting spintronics is based on the creation of spin-triplet Cooper pairs in ferromagnet-superconductor (F-S) hybrid junctions. Previous proposals to manipulate spin-polari…
Phase-coherent caloritronics with ordinary and topological Josephson junctions
Sun-Yong Hwang, Björn Sothmann
We provide a brief and comprehensive overview over recent developments in the field of phase-coherent caloritronics in ordinary and topological Josephson junctions. We start from t…
Phase-dependent heat transport in Josephson junctions with p-wave superconductors and superfluids
Alexander G. Bauer, Björn Sothmann
We investigate phase-coherent thermal transport in Josephson junctions made from unconventional superconductors or superfluids. The thermal conductance is evaluated for one- and tw…
Nonlinear chiral refrigerators
David Sanchez, Rafael Sanchez, Rosa Lopez +1
We investigate a mesoscopic refrigerator based on chiral quantum Hall edge channels. We discuss a three-terminal cooling device in which charge transport occurs between a pair of v…
