Workshop 6: Collective Phenomena in Quantum Materials

Date: Tuesday, May 21, 2019

Organizer(s): Mingda Li (MIT), Yong Cai (NSLS-II/BNL), Sara Haravifard (Duke University), Riccardo Comin (MIT), Divine Kumah (NCSU)

Location: Physics Large Seminar Room, Bldg 510


The quantum physics of systems with many constituents is qualitatively different from that with only a few. Thus, while the quantum mechanics of single atoms is largely understood, many-particle systems or systems that combine disparate elements such as photons and matter can still have completely unanticipated properties. In such systems, strong inter-particle interactions can lead to collective phenomena that are rather unintuitive and difficult to understand. As a defining feature of condensed matter, collective phenomena hosts a diverse set of exotic phases and excitations, where the best-known examples are unconventional superconductivity, emergent topological quasi-particles, and quantum spin liquid states. However, considering their complex nature, probing these phenomena are also often highly non-trivial and challenging. They mostly require highly specialized techniques and in many cases reveal that traditional concepts require to be modified and new principles need to be discovered. In light of this, the NSLS-II, by combining the coherence beam with the ultrafine resolution, offers new opportunities and unprecedented advantages for studying these collective phenomena. By focusing on a few emerging directions that might tremendously benefit from the rapid advancement of NSLS-II, this workshop will bring together scientists in the field of quantum materials to seek for the viable pathways to utilize the NSLS-II beamlines to explore a broad range of collective quantum phenomena.
