Abstract Scope	Structural symmetry breaking and recovery in condensed matter systems are closely related to exotic physical properties such as superconductivity, collective charge, and magnetic orders. The interplay between different order parameters is intricate and often subject to intense debate, as in the case of charge order and superconductivity. Recently we have applied coherent X-ray diffraction to visualize the domain structures associated with these symmetry changes directly during phase transition. In this talk, I will describe experimental challenges to push Bragg Coherent Diffractive Imaging (BCDI) into the cryogenic regime where most phase transitions in quantum materials reside. As an example, I will present our work on La1.875Ba0.125CuO4 (LBCO) where we image the structural evolution of LBCO microcrystal samples during the high-temperature tetragonal to low-temperature orthorhombic phase transition. Besides, I will show preliminary results from 34-ID-C beamline, APS to imaging Charge-order domains IrTe2 flakes, efforts towards magnetic BCDI on Sr2IrO4, and other examples.
