Superconducting Diode Effect due to Chiral Meissner Currents in a Hollow Superconducting Helix
Axel J. M. Deenen, Dirk Grundler
The superconducting diode effect (SDE) is a key nonreciprocal phenomenon with broad relevance for superconducting electronics. Using time-dependent Ginzburg-Landau simulations, we…
Vortex Refraction at Tilted Superconductor-Normal Metal Interfaces
Matéo F. L. Roinard-Chauvet, Axel J. M. Deenen, Dirk Grundler
We derive a refraction law for superconducting vortices at superconductor/normal metal interfaces. Simulations of the proximity effect under tilted geometries confirm this law and…
Tunable magnon emission from a nano-optomagnet
Anna Duvakina, Vage Karakhanyan, Mingran Xu +6
The growing demand for dense, energy-efficient, and high-frequency signal processing continues to drive device miniaturization. While downscaling remains a central challenge, magno…
Periodic phase slips and frequency comb generation at tunable microwave frequencies in superconducting diabolo structures
Axel J. M. Deenen, Dirk Grundler
Superconductors are characterized by macroscopic phase coherence and have enabled cryogenic electronics and quantum technologies. Recent advances in 3D nanofabrication now offer po…
Room temperature realization of artificial chiral magnets with reprogrammable magnon nonreciprocity at zero field
Mingran Xu, Axel J. M. Deenen, Huixin Guo +1
Chiral magnets are materials which possess unique helical arrangements of magnetic moments, which give rise to nonreciprocal transport and fascinating physics phenomena. On the one…
Nonreciprocal Spin Waves in Nanoscale Domain Walls Detected by Scanning X-ray Microscopy in Perpendicular Magnetic Anisotropic Fe/Gd Multilayers
Ping Che, Axel Deenen, Andrea Mucchietto +10
Spin wave nonreciprocity in domain walls (DWs) allows for unidirectional signal processing in reconfigurable magnonic circuits. Using scanning transmission x-ray microscopy (STXM),…
Comparing all-optical switching in synthetic-ferrimagnetic multilayers and alloys
Maarten Beens, Mark L. M. Lalieu, Axel J. M. Deenen +2
We present an experimental and theoretical investigation of all-optical switching by single femtosecond laser pulses. Our experimental results demonstrate that, unlike rare earth-t…
