Workshop on New Horizons in Quantum Correlated Materials

August 15-19, 2022 

ICTP-SAIFR, São Paulo, Brazil

Auditorium of IFT-UNESP

Home

The experimental discovery of materials displaying exotic behavior, such as unconventional superconductivity, exotic quantum orders, and nontrivial topological phases has pushed the frontiers of fundamental research in condensed matter physics. Many of the key properties of these materials emerge from the interaction between particles and the related competing energy scales. This means that they cannot be simply described by considering single-particle approximations, but require the development of new tools and nontrivial analyses.

In this workshop, we will bring together junior researchers as well as prominent experimentalists and theoreticians to discuss low dimensionality effects, frustrations, spin-orbit coupling, charge fluctuations, superconductivity, and disorder in strongly correlated systems. We expect a rich exchange of ideas during the workshop and the possible establishment of new collaborations between the participants.

Participants are invited to present their works in the poster section, and depending on the schedule, a few contributed works will be considered for oral presentations. 

There is no registration fee.
