abstract

The idea that many body systems in complex materials may self-organize under highly non-equilibrium conditions suggests that entirely new emergent states with new and unexpected functionalities might be created in this way. The route for creation of such states is not limited to symmetry-breaking phase transitions, and entirely novel mechanisms may come into play. I will discuss recent experimental findings of mesoscopically textured topologically protected metastable states created through density-driven non-equilibrium transitions. Combining ultrafast optical pulse excitation with scanning tunneling microscopy under various non-equilibrium conditions we find various intertwined electronic orders and metastable amorphous electronic states stabilized in real space by non-trivial topological defects. The relaxation of these states reveals a novel state of configurational quantum electronic matter that may find its uses in ultrafast memory devices.
