Title: Visualizing Strongly Interacting Quantum Matter in Two-dimensional Materials

Abstract: 
The advent of two-dimensional materials and their stacks have revolutionized our ability to engineer novel states of matter, especially those with strong interaction and topological properties. The ability to visualize these states with the scanning tunneling microscopy and related techniques materials are also making it possible to study interacting systems from unprecedented microscopic perspective. In this talk, I will describe some of these experiments that include direct visualization of Wigner crystal phases and study of fractional quantum Hall states with high spatial and energy resolution. I will also describe how these experiments created the opportunity to probe single anyons and their novel properties.
