Functional Nanoscale Phase Separation and Intertwined Order in Quantum Complex Materials

Abstract

Nanoscale phase separation (NPS) characterized by particular types of correlated disorder plays an important role in the functionality of high temperature superconductors (HTS). Our results show that multiscale heterogeneity is an essential ingredient of quantum functionality in complex materials. Here, the interactions developing between different structural units cause dynamical spatiotemporal conformations with correlated disorder. Thus visualizing conformations landscape is needed for understanding the physical properties of complex matter and requires advanced methodologies based on high precision X ray measurements. We discuss the dynamical correlated disorder at nanoscale and the related functionality in oxygen doped perovskite superconducting materials
