The Majorana STM as a perfect detector of odd-frequency superconductivity
Oleksiy Kashuba, Björn Sothmann, Pablo Burset +1
We propose a novel scanning tunneling microscope (STM) device in which the tunneling tip is formed by a Majorana bound state (MBS). This peculiar bound state exists at the boundary…
Optimal quantum interference thermoelectric heat engine with edge states
Peter Samuelsson, Sara Kheradsoud, Björn Sothmann
We show theoretically that a thermoelectric heat engine, operating exclusively due to quantum-mechanical interference, can reach optimal linear-response performance. A chiral edge…
High efficiency thermal switch based on topological Josephson junctions
Björn Sothmann, Francesco Giazotto, Ewelina M. Hankiewicz
We propose theoretically a thermal switch operating by the magnetic-flux controlled diffraction of phase-coherent heat currents in a thermally biased Josephson junction based on a…
Three-Terminal Energy Harvester with Coupled Quantum Dots
Holger Thierschmann, Rafael Sánchez, Björn Sothmann +5
Rectification of thermal fluctuations in mesoscopic conductors is the key idea of today's attempts to build nanoscale thermoelectric energy harvesters in order to convert heat into…
Fingerprint of topological Andreev bound states in phase-dependent heat transport
Björn Sothmann, Ewelina M. Hankiewicz
We demonstrate that phase-dependent heat currents through superconductor-topological insulator Josephson junctions provide a useful tool to probe the existence of topological Andre…
