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…
Finite Length Effects and Coulomb Interaction in Ge Quantum Well-Based Josephson Junctions Probed with Microwave Spectroscopy
S. C. ten Kate, D. C. Ohnmacht, M. Coraiola +10
Proximitized Ge quantum wells have emerged as a novel platform for studying Andreev bound states (ABSs), due to their expected strong spin-orbit interaction and high mobility. Here…
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…
Specular-Andreev reflection and Andreev interference in an Ising superconductor junction
Gaoyang Li, Sourabh Patil, Yanxia Xing +2
Being resilient to magnetic field, Ising superconductor serves as an exceptional platform for studying the interplay between superconductivity and magnetism. In this Letter, we fir…
Reflectionless modes as a source of Weyl nodes in multiterminal Josephson junctions
David Christian Ohnmacht, Valentin Wilhelm, Wolfgang Belzig
Multiterminal Josephson junctions are a promising platform to study non-trivial topology in engineered quantum systems. Yet, experimentally meaningful insight into what exactly mak…
Multiterminal Josephson junctions with tunable topological properties
Panch Ram, Detlef Beckmann, Romain Danneau +1
Since the discovery of the Andreev reflection process at normal-metal/superconductor junctions and the corresponding Andreev bound states in superconductor/normal-metal/superconduc…
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…
Zero-temperature phase-flip rate in a biased parametric oscillator
Daniel K. J. Boneß, Wolfgang Belzig, Mark I. Dykman
A parametrically driven oscillator has two stable vibrational states at half the modulation frequency. The states have opposite phase and equal amplitudes. An extra drive at half t…
