Description
Spatiotemporal correlations stabilize exotic phases of quantum materials. Here I present recent results from resonant soft coherent scattering experiments on the Smectic-like to Nematic-like phase transition in amorphous $\rm Fe_{51}Ge_{49}$. By combining synchrotron measurements from the Advanced Light Source and free electron laser measurements from the Linearly Coherent Light Source, we have found a region of instability as a precursor to the Nematic-like phase where fluctuations coexist on the timescale of both minutes and sub-nanoseconds. These results emphasize the general nature of multi-step and multi-time scale topological phase transitions and are likely applicable to a broad class of materials and phenomena.
