DESCRIPTION:Few equilibrium—even less so nonequilibrium—statistical-me
 chanical models with continuous degrees of freedom can be solved exactly. 
 Classical equilibrium hard spheres in infinitely many space dimensions are
  a notable exception. Even in the absence of a Boltzmann distribution\, an
 d in infinite dimensions\, we can exactly compute the nonequilibrium stead
 y state properties that govern and characterize the collective behavior of
  active hard spheres (the structure factor\, the equation of state for the
  pressure). We determine the crowding density at which the effective self-
 propulsion of a particle vanishes. We finally compare this crowding densit
 y to other jamming scales previously identified in (equilibrium) hard-sphe
 res.\n\n[after a joint work with T. Arnoulx de Pirey & G. Lozano]
