Equidistant versus bipartite ground states for 1D classical fluids at fixed particle density
Laurent Bétermin, Ladislav Å amaj, Igor TravÄnec
We study the ground-state properties of one-dimensional fluids of classical (i.e., non-quantum) particles interacting pairwisely via a potential, at the fixed particle density …

Structural transitions in interacting lattice systems
Laurent Bétermin, Ladislav Å amaj, Igor TravÄnec
We consider two-dimensional systems of point particles located on rectangular lattices and interacting via pairwise potentials. The goal of this paper is to investigate the phase t…
