Kickoff Workshop on Topology and Quantum Phases of Matter

On August 27-28, 2018, the CMSA will be hosting a Kickoff workshop on Topology and Quantum Phases of Matter. New ideas rooted in topology have recently had a big impact on condensed matter physics, and have highlighted new connections with high energy physics, mathematics and quantum information theory. Additionally, these ideas have found applications in the design of photonic systems and of materials with novel mechanical properties. The aim of this program will be to deepen these connections by fostering discussion and seeding new collaborations within and across disciplines.

This workshop is a part of the CMSA’s program on Program on Topological Aspects of Condensed Matterand will be the first of two workshops, in addition to a visitor program and seminars.
