Research overview

Theoretical Condensed Matter Physics.

My main research interests are in the field of low dimensional systems and nanostructures, whose properties are shaped by the effect of electron interactions. Many of the topics I explore are motivated by the long-term goal of bringing quantum effects to applications such as quantum computing. My recent activities involve the study of self-organisation of magnetic moments in electron conductors leading to helical and topological phases and entanglement detection in nanostructures.
