Nonreciprocal Magnon Hanle Effect in Antiferromagnetic -FeO
Janine Gückelhorn, Sebastián de-la-Peña, Monika Scheufele +8
The precession of the magnon pseudospin about the equilibrium pseudofield, the latter capturing the nature of magnonic eigenexcitations in an antiferromagnet, gives rise to the mag…
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…
Sextets in four-terminal Josephson junctions
Miriam Rike Ebert, David Christian Ohnmacht, Wolfgang Belzig +1
Multiterminal superconducting junctions have revitalized the investigation of the Josephson effect. One of the most interesting aspects of these hybrid systems is the occurrence of…
Nonclassical Photon-Assisted Transport in Superconducting Tunnel Junctions
Matthias Hübler, Juan Carlos Cuevas, Wolfgang Belzig
Advances in circuit quantum electrodynamics have enabled the generation of arbitrary nonclassical microwave states and paved the way for addressing novel physics questions. Here, w…
Exploring the energy spectrum of a four-terminal Josephson junction: Towards topological Andreev band structures
Tommaso Antonelli, Marco Coraiola, David Christian Ohnmacht +10
Hybrid multiterminal Josephson junctions (JJs) are expected to harbor a novel class of Andreev bound states (ABSs), including topologically nontrivial states in four-terminal devic…
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…
Flux-Tunable Josephson Diode Effect in a Hybrid Four-Terminal Josephson Junction
M. Coraiola, A. E. Svetogorov, D. Z. Haxell +10
We investigate the direction-dependent switching current in a flux-tunable four-terminal Josephson junction defined in an InAs/Al two-dimensional heterostructure. The device exhibi…
Quartet Tomography in Multiterminal Josephson Junctions
David Christian Ohnmacht, Marco Coraiola, Juan José García-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…
Phase-engineering the Andreev band structure of a three-terminal Josephson junction
M. Coraiola, D. Z. Haxell, D. Sabonis +11
In hybrid Josephson junctions with three or more superconducting terminals coupled to a semiconducting region, Andreev bound states may form unconventional energy band structures,…
Microwave-induced conductance replicas in hybrid Josephson junctions without Floquet-Andreev states
D. Z. Haxell, M. Coraiola, D. Sabonis +9
Light-matter interaction enables engineering of non-equilibrium quantum systems. In condensed matter, spatially and temporally cyclic Hamiltonians are expected to generate energy-p…
Enhancing Near-Field Radiative Heat Transfer with Si-based Metasurfaces
Víctor Fernández-Hurtado, Francisco J. Garcia-Vidal, Shanhui Fan +1
We demonstrate in this work that the use of metasurfaces provides a viable strategy to largely tune and enhance near-field radiative heat transfer between extended structures. In p…
Geometry-related magnetic interference patterns in long SNS Josephson junctions
F. Chiodi, M. Ferrier, S. Guéron +5
We have measured the critical current dependence on the magnetic flux of two long SNS junctions differing by the normal wire geometry. The samples are made by a Au wire connected t…
