We have pushed Bragg Coherent Diffractive Imaging (BCDI) into the cryogenic regime where most phase transitions in quantum materials reside. Utilizing coherent photons at 34-ID-C beamline of the Advanced Photon Source, we studied the low-temperature phases of the classical cuprate superconductor La2-xBaxCuO4. These phases break the local four-fold rotational symmetry of its high temperature tetragonal (HTT) structure. Our preliminary data suggests the low-temperature-orthorhombic (LTO) phase is not pinned to local crystal disorder or defects. We will briefly discuss the relation between LTO and the charge order.
