САЖЕТАК:
Over the past few decades, the field of quantum materials has rapidly expanded to take condensed matter physics community by storm. The term quantum materials encompasses a wide range of solids, including correlated electron systems, unconventional superconductors, topological quantum matter and 2D Moire systems. In these materials, electron charge, spin, and orbital degrees of freedom intertwine to generate new phenomena, often in the presence of non-trivial band topology. In this talk, we will describe several examples of how we can use spectroscopic imaging scanning tunneling microscopy and molecular beam epitaxy to explore emergent electronic phenomena in quantum solids at single atom length scales. We will present our work that enabled visualization of inhomogeneous spin and charge orders in high-temperature superconductors [1, 2] and iridium-oxides [3, 4]. We will then discuss our recent experiments focused on discovering symmetry-breaking orders [5-8] and Berry curvature effects [9, 10] in newly discovered Kagome metals. We will conclude with brief remarks on the prospects for future studies.
