Brownian electric bubble quasiparticles

ORAL

Abstract

In this talk I will describe our theoretical predictions on the possibility to stabilize a new kind of quasiparticle in ferroelectric nanostructures, by suitably controling the elastic and electric

boundary conditions. These novel particles are electric bubbles (e-bubbles) that present a non-trivial topology at low temperatures (skyrmion-like) and become spontaneously mobile upon moderate heating (Brownian diffusion). I will discuss the typical features and time scales for the e-bubble dynamics, as well as the basic inter-bubble interactions. I will conclude by giving a brief outlook of the field.
