Balatsky, Nordic Institute for Theoretical Physics and The University of Connecticut We are thankful for the support from the University of North Florida, University of Connecticut, Nordic Institute for Theoretical Physics, and Asia-Pacific Center for Theoretical Physics December 14 – 16, 2020 2 Dynamic Quantum Matter and Materials Introduction Quantum matter and materials, like topological states, 2D materials, and Dirac and Weyl materials have grown to be an active area of modern condensed matter. Fascinating properties of quantum materials might lead to technological applications such as spintronics, quantum technologies, and quantum sensors. The combination of new materials discoveries and the development of new probes of quantum matter has helped shape these topics into an exciting area. Recent dynamic and pumped probe experiments reveal a strong promise of Dynamic Quantum Matter as a new research direction. We strive to measure, understand, and predict transient correlations and coherences in quantum materials upon different driving conditions. Therefore, we introduce it as a new topic for this year’s quantum matter conference. We seek to actively discuss hidden, entangled, and dynamic orders that emerge in quantum materials and matter. The main focus for this upcoming conference will be on the modeling and experimental observations of Dynamic Quantum Matter and Materials (DQMM). Overall, this workshop aims to bring together researchers to discuss and highlight emerging topics and develop ideas for future research.
