Equidistant versus bipartite ground states for 1D classical fluids at fixed particle density

Laurent Bétermin, Ladislav Šamaj, Igor Travěnec

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 Šamaj, Igor Travěnec

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…

1D fluids with repulsive nearest-neighbour interactions: Low-temperature anomalies

Igor Travěnec, Ladislav Šamaj

A limited number of 2D and 3D materials under a constant pressure contract in volume upon heating isobarically; this anomalous phenomenon is known as the negative thermal expansion…

Contact value theorem for electric double layers with modulated surface charge density

Ladislav Å amaj

The contact value theorem was originally derived for Coulomb fluids of mobile charged particles in thermal equilibrium, in the presence of interfaces carrying a {\em uniform} surfa…

A strong-coupling effective-field theory for asymmetrically charged plates with counterions only

L. Samaj, E. Trizac, M. Trulsson

We are interested in rationalizing the phenomenon of like-charge attraction between charged bodies, such as a pair of colloids, in the strong coupling regime. The two colloids are…
