Complete Suppression of Thermomagnetic Instabilities in Nb Superconducting Films by Combined Metallic Layers and Ion Irradiation
D. Carmo, A. M. H. de Andrade, R. Giulian +3
Thermomagnetic instabilities in superconducting films can trigger flux avalanches that disrupt the critical state and impair the performance of superconducting devices. Here we inv…

Finding the ultra-narrow electric quadrupole transition in Ni ion for an optical clock
Charles Cheung, Sergey G. Porsev, Dmytro Filin +7
The Ni ion features an electronic transition with a natural width of only 8 mHz, allowing for a highly stable optical clock. We predict that the energy of this strongly for…
