ABSTRACT:

Many fascinating phenomena in nature owe their emergence from the interactions of large number of particles. In particular, symmetry, interaction and topological effects dominate many of the quantum properties of reduced-dimensional systems. These effects often lead to manifestation of counter-intuitive concepts and phenomena that may not be so prominent or have not been seen in the bulk. In this talk, I present some fascinating quantum phenomena discovered in recent studies of atomically thin one- and two-dimensional materials. A number of interesting and unexpected behaviors have been found – e.g., strongly bound excitons (electron-hole pairs) with unusual energy level structures; tunable magnetism and plasmonic properties; novel topological phases; correlated 3- and 4-particle excitations; etc. – adding to the promise of these materials for exploration of new science and valuable applications.

 

STEVEN GWON SHENG LOUIE is a computational condensed-matter physicist. He is a professor of physics at the University of California, Berkeley and senior faculty scientist in the Materials Sciences Division at Lawrence Berkeley National Laboratory, where his research focuses on nanoscience. He is honored with numerous awards including 2019 Fellow of Materials Research Society (MRS) and 2018 Kodosky Lecturer at Rensselaer Polytechnic Institute. Professor Louie’s research spans a broad spectrum of topics in theoretical condensed matter physics and nanoscience. He is known for his pioneering work on the ab initio GW method, which led to his resolution of the bandgap problem in semiconductors and founding of the field of first-principles study of excited-state properties of materials, and for his seminal work on surfaces and interfaces, nanostructures, and reduced-dimensional systems. He was a founding scientific director of the Molecular Foundry, a DOE national nanoscience center. He is identified by the ISI Web of Science as one of the most highly cited researchers in physics and nanoscience.
