A Uniqueness Result for Minimizers of the 1D Log-gas Renormalized Energy
arXiv:1408.2283
Abstract
Sandier and Serfaty studied the one-dimensional Log-gas model, in particular they gave a crystallization result by showing that the one-dimensional lattice is a minimizer for the so-called renormalized energy which they obtained as a limit of the -particle Log-gas Hamiltonian for . However, this minimizer is not unique among infinite point configurations (for example small perturbations of leave the renormalized energy unchanged). In this paper, we establish that uniqueness holds at the level of (stationary) point processes, the only minimizer being given by averaging over a choice of the origin in . This is proved by showing a quantitative estimate on the two-point correlation function of a process in terms of its renormalized energy.
