DESCRIPTION:Prof. Antoine GEORGES\, Collège de France\, Paris - Flatiron 
 Institute\, New York - Université Genève\nThe Hubbard model is a paradig
 m of the `strong correlation problem’\, with relevance to high-Tc superc
 onductors and ultra-cold atoms. Key aspects of its physics in two dimensio
 ns can now be established beyond doubt\, thanks to the development of cont
 rolled and accurate computational methods working in synergy (such as quan
 tum embedding\, tensor networks\, various flavors of quantum Monte Carlo a
 nd\, recently\, neural quantum states). I will present in this perspective
  how the `pseudogap’ can be understood in both the weak and strong coupl
 ing regimes and review the current understanding of emerging competing ord
 ers at low temperature such as d-wave superconductivity or stripes.
