The Bragg glass phase is a near-perfect crystalline phase with glassy characteristics that is expected to occur in vortex lattices and charge density wave systems in the presence of disorder. 

In a paper published in Nature Physics, Krishnanand Mallayya, Eun-Ah Kim and others from Cornell University in the United States proposed the bulk probe evidence of Bragg glass phase in the system disordered charge density wave material PdxErTe3.

Using X-ray data and a machine learning-based analytical tool called X-ray diffractiontemperature clustering (X-TEC), divergent correlation lengths in samples with moderate intercalation are established over a wide temperature range.

To achieve this analysis, a high-throughput measurement of inverse correlation length, called peak spread, is also introduced. The detection of order in Bragg glass and the resulting phase diagram advance the understanding of the complex interplay between disorder and fluctuation. Based on this analytical technique, targeting quantum fluctuations through high-throughput measurements of peak diffusion can revolutionize the study of quantum fluctuations in scattering experiments.
