Safety Measures:


Nothing is more important than your health and well-being at RCQM events. Masks will be required for all indoor activities and please consider fellow attendees’ comfort levels when it comes to distancing. All in-person attendees are expected to be fullly vaccinated. 

The workshop will observe all the covid-19 protocols mandated by Rice University (e.g., face masks are required indoors, food will be served in individual portions, social distancing is encouraged), and take measures according to the applicable CDC and Harris County guidelines.


Here are the evolving covid curves in

and at Rice https://coronavirus.rice.edu/

 

Rationale and Scope: 

There have been extensive recent advancements on topological materials, both in weakly correlated settings and in strongly interacting systems. Among these are discovery and exploration of new topological states of matter and their transitions to nearby quantum phases. The breadth of the field calls for interactions among the different sub-communities. This workshop aims to bring together top experts from these communities to highlight the recent achievements in each area, and to provide a forum for cross-talk among the subjects. 

The workshop will revolve around the following focus areas in the overarching field of Topological Materials: 

-         Symmetry-protected Semimetals

-         Topological States in Magnets and Superconductors

-         Topological States Driven by Strong Correlations

-         Strong Correlation Physics for Topology

-         Tuning Topological States

-         Diverse Materials and Broader Contexts 

 

 

Tentative List of Sessions: 

Recent developments on band topology

Topological metals driven by strong correlations

Topology in magnetic systems

Topological superconductors

Tuning topological states

Graphene moiré bands

Diverse materials

Broader contexts: from materials to information

 

Format: 

The workshop will last for two days, incorporating 30min invited speaker slots as well as two poster sessions. Several contributed talks will be selected from submitted posters. 

 

Organizers:

Pengcheng Dai        (Rice University)

Matt Foster             (Rice University)

Qimiao Si                (Rice University)
