Perspective on the Vortex Mass Determination in Superconductors using Circular Dichroism
Roman Tesař, Michal Šindler, Pavel Lipavský +2
The effective mass of Abrikosov vortices in superconductors remains a challenging problem with limited experimental verification. In this paper, we present a method based on observ…
