Giant magnon spin conductivity in ultrathin yttrium iron garnet films

XY Wei, OA Santos, CHS Lusero, GEW Bauer… - Nature Materials, 2022 - nature.com
Conductivities are key material parameters that govern various types of transport (electronic
charge, spin, heat and so on) driven by thermodynamic forces. Magnons, the elementary …

A solid-state platform for cooperative quantum phenomena

X Li, B Flebus, J Marino, D Chang - Bulletin of the American Physical Society, 2024 - APS
The dissipation stemming from the coupling of a system with its environment is not always
detrimental to quantum phenomena; in fact, it can be harnessed as a valuable resource. For …

Superconductivity-enhanced magnetic field noise

SP Kelly, Y Tserkovnyak - arXiv preprint arXiv:2412.05465, 2024 - arxiv.org
