| contents | Ultrafast optical excitations allow creating new metastable and hidden states in quantum materials. However, the fundamental material properties required to support new emergent order are largely unknown. Here we show for two colossal magnetoresistive (CMR) manganites that electronic phase separation (EPS) strongly favors non-thermal behavior and exploit this to stabilize an optically-induced conducting state. Our results shed light on the role of EPS in optical control of CMR manganites and provide guidance for the design of materials that can exhibit non-equilibrium states of matter. |
