Abstract: Emergent phenomena such as high temperature superconductivity and correlation-driven insulators have inspired research into quantum materials for several decades. In the past decade, fundamental progress in our understanding of symmetry and topology due to the strong correlation in solids has given a new direction to this research. Advanced experimental methodologies such as Scanning Probe Microscopy (SPM) have evolved as a consequence of these materials discoveries, and these new tools give us unprecedented insight into the quantum nature of the ground and excited states. Scanning Tunneling Microscopy (STM) has become a pivotal tool in the past two decades, providing intricate electronic details through high-energy resolution spectroscopy and subatomic-level imaging. In this presentation, I'll delve into a diverse array of correlated states characterized by rotational and/or translational symmetry breaking—such as antiferromagnetic order, charge density waves, and pair density waves—probed using advanced STM techniques across various families of correlated quantum materials. Ultimately, I'll provide a concise overview of several cutting-edge STM techniques tailored for various aspects of investigating the properties of quantum materials.
