Background and activities

Hi, I am theoretical condenced matter physicist. During my PhD, I have so far focused on superconductivity and superconducting heterostructures. In these heterostructures, I have studied the interplay between superconductivity, ferro- and antiferromagnetism, and spin-orbit interaction.
