Scientific Calendar Event



Description
An ICTP meeting in person

In collaboration with the Simons Foundation

The conference aims to bring together communities working on quantum fluids such as spin liquids, unconventional superconductors, and fractional quantum Hall states where emergent gauge fields, fractionalization, and topological order, all of which find their root in the RVB paradigm, play the pivotal role.

Founded nearly fifty years ago, the concept of resonating valence bonds (RVBs) for Mott insulators established a paradigm which branched out throughout correlated electron systems and adjacent fields. Looking at the frontier of contemporary condensed matter physics, several directions of quantum fluid states have surfaced where emergent gauge fields, fractionalization, and topological order, all of which find their root in the RVB paradigm, play the pivotal role. It spans across a plethora of topics as diverse as spin liquids, unconventional superconductors, and fractional quantum Hall effect. In this conference, we aim at bringing these communities together, using the RVB paradigm as the common thread between them. As such, we aim at reaching an interactive exchange between those different subfields, and thus a stimulating environment for creating new ideas. Keeping in mind the current trends, we plan to cover the following exciting directions:


Topics:
  • Kitaev Spin Liquids – models and materials
  • Pyrochlore magnets
  • Cuprate Superconductors
  • Sachdev-Ye-Kitaev (SYK) model
  • Kagome magnets
  • Fractional Quantum Hall effect and Chiral spin liquids
