DESCRIPTION:Speaker: Mathieu Lewin\nhosted by Robert Seiringer\nAbstract: F
 or a given one-particle density\, we consider the distribution of classica
 l electrons that reproduces this density and minimizes the Coulomb energy.
  This is an optimal transport problem. In this talk we ask whether we can 
 do better by allowing the number of electrons to fluctuate (grand-canonica
 l problem) and\, if so\, what is the optimal range of fluctuation. An answ
 er to these questions gives a counterexample to a famous conjecture for qu
 antum electrons. Collaboration with Simone Di Marino (Genova) and Luca Nen
 na (Paris-Saclay).
