Time & Location
About The Event
NOTICE: Postponed to November 15-17, 2021. Please visit the website: https://rcqm.rice.edu/events/99/. There will be a virtual mini-workshop on April 26 - 29. Register now at: https://riceuniversity.zoom.us/meeting/register/tJcqfuqvrDMsG9y4-igxscWcAXz9k8i1GLlC.
Topological matter in weakly correlated electrons has seen major advances in recent years. Examples include the discovery of “higher-order” topological insulators and their potential realization in bismuth, Weyl semimetals in magnetically ordered materials, and indications of topological states of magnons. Meanwhile, rapid progresses have taken place during the last couple of years in exploring electronic topology of strongly correlated systems. Examples include the discovery of strongly correlated Weyl semimetals in heavy fermion materials, progresses in the search for signatures of topological states in Kondo insulators and iron-based superconductors. For the most part, the two directions have been developing with very limited crosstalk. Now is a particularly opportune time to foster active dialogues between the two communities. The workshop aims to realize this goal by bringing together key players interested in topological materials from the communities of both weak and strong correlations. To enhance the opportunities for crosstalk, it will feature a variety of materials, ranging from non-interacting systems involving sp-electrons, strongly correlated compounds based on d-and f-electrons, engineered structures including graphenelayers, liquid He3 and ultracold atoms.
The main topics will include:
- Recent developments on weakly correlated topological states with time-reversal symmetry,
- Weakly interacting topological phases in magnetically ordered systems,
- Topological states driven by strong correlations,
- Novel strong correlation physicswith the potential to impact on topological matter
- Tuning of topological states
- Topological physics in diverse materials and broad contexts
