Over the recent decades there has been tremendous progress in understanding and
controlling friction between surfaces in relative motion. However the complex nature of the …

Friction is the oldest branch of non-equilibrium condensed matter physics and, at the same
time, the least established at the fundamental level. A full understanding and control of …

The possibility to achieve entirely frictionless, ie, superlubric, sliding between solids holds
enormous potential for the operation of mechanical devices. At small length scales, where …

Phonon spectra of a two-dimensional (2D) solid dusty plasma modulated by 2D square and
triangular periodic substrates are investigated using Langevin dynamical simulations. The …

The superlubric-pinned transition in the depinning dynamics of a two-dimensional (2D) solid
dusty plasma modulated by 2D triangular periodic substrates is investigated using Langevin …

The understanding of friction at nano-scales, ruled by the regular arrangement of atoms, is
surprisingly incomplete. Here we provide a unified understanding by studying the …

We present a numerical investigation of the size scaling of static friction in incommensurate
two-dimensional contacts performed for different lateral loading configurations. Results of …

In a density-imbalanced bilayer Wigner crystal, where the ratio of electron densities in
separate layers deviates slightly from unity, defects spontaneously form in one or both layers …

We study a two-dimensional model for interacting colloidal particles which displays
spontaneous clustering. Within this model we investigate the competition between the …

Molecular dynamics simulations are reported for the structural and thermodynamic
properties of submonolayer xenon adsorbed on the (111) surface of platinum for …
