The Independence on Boundary Conditions for the Thermodynamic Limit of Charged Systems
David Hasler, Jan Philip Solovej
We study systems containing electrons and nuclei. Based on the fact that the thermodynamic limit exists for systems with Dirichlet boundary conditions, we prove that the same limit…
