Organized by Yale University, University of Connecticut, Nature Physics, Nature Reviews Materials and Nature Materials.

A major issue in condensed-matter physics is the competition between ordered states with different symmetries and properties. For instance, in oxide superconductors unconventional superconductivity competes with charge orders, while moiré graphene's phase diagram shows various insulating states driven by correlations or topology. Ultrafast perturbations can disrupt the balance between these phases, leading to transient or metastable states. Models such as the Hubbard model simplify experimental complexity to aid theoretical study. 

This Nature Conference will: 

• Examine the competition between different states from various perspectives.
• Feature sessions on 2D materials and nickelate superconductors.
• Survey recent experiments using ultrafast probes of quantum materials.
• Discuss quantum simulation using 2D materials.
• Explore the synthesis and characterization of samples exhibiting this physics.
