Current cross-correlations as probes for poor man's Majorana states
Saatwik Patnaik, Aditya Saran, Himadri S Dhar +3
The minimal Kitaev chain that emulates a topological superconductor with three quantum dots offers a tunable platform for potentially hosting poor man's Majorana (PMM) modes. Asser…
High-field Josephson effect enabled by a moiré Hofstadter spectrum
A. DÃez-Carlón, M. Cárdenes Wuttig, N. Wei +7
The paper demonstrates that graphene/hBN Josephson junctions engineered with a moiré superlattice can maintain phase‑coherent superconducting transport at magnetic fields up to 6 T…
Magneto-Chiral Anisotropy in Josephson Diode Effect of All-Metallic Lateral Junctions with Interfacial Rashba Spin-Orbit Coupling
Maximilian Mangold, Lorenz Bauriedl, Johanna Berger +7
We explore the role of interfacial Rashba spin-orbit coupling (SOC) for the Josephson diode effect in all-metal diffusive Josephson junctions. Devices with Fe/Pt and Cu/Pt weak lin…
Controllable Superconductivity in Suspended van der Waals Materials
Ruihuan Fang, Cuiju Yu, Youqiang Huang +12
Tunable superconductors provide a versatile platform for advancing next-generation quantum technologies. Here, we demonstrate controllable superconductivity in suspended NbSe2 thin…
Microwave photon detection at parametric criticality
Kirill Petrovnin, Jiaming Wang, Michael Perelshtein +2
The detection of microwave fields at single-photon power levels is a much sought-after technology, with practical applications in nanoelectronics and quantum information science. H…
Steady-state dynamics and non-local correlations in thermoelectric Cooper pair splitters
Arnav Arora, Siddhant Midha, Alexander Zyuzin +2
Recent experiments on Cooper pair splitters using superconductor-quantum dot hybrids have embarked on creating entanglement in the solid-state, by engineering the sub-gap processes…
