Asymptotic energy of lattices

Yan, Weigen; Zhang, Zuhe - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 8, pp. 1463-1471

The energy of a simple graph G arising in chemical physics, denoted by E(G), is defined as the sum of the absolute values of eigenvalues of G. As the dimer problem and spanning trees problem in statistical physics, in this paper we propose the energy per vertex problem for lattice systems. In...
