Overview

Strongly correlated quantum materials provide a fertile ground for novel quantum phases and unusual excitations. The developments in recent years have considerably expanded the frontiers of the field. Correlated topological states arise in materials with both strong correlations and large spin-orbit coupling. Signatures of quantum spin liquids appear in a flurry of new magnetic systems. Quantum criticality and strange metal behavior develop near a broad range of electronic orders. Considerable new insights are gained in the understanding of high temperature or otherwise unconventional superconductors. Engineered low-dimensional structures provide unexpected settings for the interplay between strong correlations and superconductivity. Finally, surprising properties are found in correlated systems driven out of equilibrium. The workshop will showcase these exciting developments. It will bring together key researchers active in the broad range of topics, promote crosstalk among the sub-communities, and highlight the emerging principles that may apply across the different materials classes. To realize these goals, the speakers will be instructed to emphasize on open questions, perspectives and outlooks.

 

Specific topics will include:

  • Strongly correlated topology

  • Quantum magnetism, including multiferroics

  • Quantum criticality and strange metals

  • High temperature superconductivity in copper-and iron-based materials

  • Unconventional superconductivity in heavy fermion and related systems

  • Correlated systems out of equilibrium

  • Correlated 2D materials, especially twisted graphene layers

The topics have been chosen with a view to both the level of excitement and the pace of advances that have been made in recent years, as well as by the potential for cross fertilization that has not been adequately stimulated by conferences and workshops. For example, recent dramatic developments in 2D materials have provided a new platform to study the interplay between strong correlations and superconductivity, and we intend to engage the researchers working on such low-dimensional systems to fully interact with the bulk correlated-electron community. Likewise, there tends to be separation of meetings on quantum magnetic systems for multiferroics from those of the correlated-electron community, and we intend to help bridge this divide. As another example, recent developments highlight a significant growth in the interest of the correlated-electron researchers on topological states. The potential of such activities to impact on the overall development of strong correlation physics can be enhanced by having these developments discussed in the broad correlated-electron community.
