Stereochemical Vacuum Gap Explains Out-of-Plane Thermal Insulation in MXenes
O. Mateos-Lopez, J. G. Vilhena, Isaac Armstrong +3
Two-dimensional MXenes are promising materials for thermal management and spectral camouflage, combining low out-of-plane thermal conductivity with low infrared emissivity and mech…
Yu-Shiba-Rusinov States in Ising Superconductors
Michael Hein, Juan Carlos Cuevas, Wolfgang Belzig
The nature of the superconducting state in two-dimensional transition-metal dichalcogenides remains under active debate. A widely used description invokes so-called \textit{Ising s…
Transparency-controlled multiple charge transfer in superconducting junctions with local shot-noise scanning tunneling spectroscopy
Yudai Sato, Maialen Ortego Larrazabal, Jian-Feng Ge +6
Charge transport in superconducting junctions at finite voltages is governed by Andreev reflections, including multiple Andreev reflections, which are processes that enable multipl…
The role of charge in thermodynamic uncertainty relations
David Christian Ohnmacht, Wolfgang Belzig, Juan Carlos Cuevas
We demonstrate that the charge value of transport mechanisms heavily impacts the validity of thermodynamic uncertainty relations (TURs). Specifically, we show within the framework…
Thermodynamic uncertainty relations in superconducting junctions
David Christian Ohnmacht, Juan Carlos Cuevas, Wolfgang Belzig +3
Quantum conductors attached to metallic reservoirs have been demonstrated to overcome the thermodynamic uncertainty relation (TUR), a trade-off relation between the amount of dissi…
Quartet Tomography in Multiterminal Josephson Junctions
David Christian Ohnmacht, Marco Coraiola, Juan José GarcÃa-Esteban +4
We investigate the detection of quartets in hybrid multiterminal Josephson junctions. Using simple models of quantum dots coupled to superconducting leads, we find that quartets ar…
