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…
Chirality Imprinting and Spin-texture Tunability in Conformally Coated 3D Magnetic Nanostructured Metamaterials
Alexander Roberts, Huixin Guo, Joseph Askey +4
Three-dimensional (3D) magnetic nanostructures offer unprecedented opportunities for engineering emergent spin textures, but controlling their configuration remains a central chall…
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…
Controlling spin currents with magnon interference in a canted antiferromagnet
Lutong Sheng, Anna Duvakina, Hanchen Wang +16
Controlling spin current lies at the heart of spintronics and its applications. The sign of spin currents is monotonous in ferromagnets once the current direction is determined. Sp…
