RESEARCHER IN ATOMISTIC MODELLING OF FERROELECTRIC DYNAMICS (m/f)

How will you contribute?Get ready to dive into the captivating realm of ferroelectrics, where surprises at the nanoscale await discovery! We are thrilled to announce a unique opportunity for a curious and skilled Postdoctoral Researcher to join our dynamic team.Ferroelectrics continue to mesmerize at the nanoscale. By inducing electrostatic or mechanic frustration on them, we can unlock a rich tapestry of dipole structures, including skyrmions and vortex lattices. Such polar textures are a hot research topic and offer a dual promise. First, their origin and behaviour pose intriguing questions begging for answers. Second, they hold great potential for groundbreaking applications, from outstanding voltage amplifications to shaping the future of 6G technologies.In the realm of ferroelectric ultrathin films, we are facing new challenges. Applying an electric bias transforms the dipole landscape, giving rise to confined nanoregions (bubbles) with a polarization opposite to their embedding matrix. These bubbles are electric versions of magnetic skyrmions, and are more than just a rarity; they constitute a novel quasiparticle in their own right. Recent experimental observations and successful manipulation attempts have set the stage. Yet, their dynamical behaviour remains a largely unexplored frontier. Lately our group at LIST predicted that electric bubbles will display Brownian motion and that this motion can be harnessed to produce bubble currents.We offer you a postdoc position in the project “Bubblaced”, led by Hugo Aramberri ( ), and focused on the modelling of electric bubble quasiparticles. You will join the ongoing work by Hugo Aramberri and Jorge Íñiguez-González (also involved in the project) on understanding these objects using second-principles atomistic simulation methods, focusing on their dynamics and possible ways to act on them. You will also benefit from interactions with other team members. Join us in exploring the fascinating world of electric bubbles! Is Your profile described below? Are you our future colleague? Apply now!• You hold a PhD in Condensed Matter Physics, Materials Science, Computational Physics, Chemistry, or a closely related field.• You have hands-on experience with atomistic modelling (DFT, second-principles, machine-learned force fields), scripting for automation and data analysis (e.g. Python, Bash), and working in a Linux/HPC environment.
