Frictional stick-slip dynamics is studied theoretically and numerically in a model of one oscillator interacting with a nonsinosoidal subtracted potential. We focus our attention on a class of parameterised one-site Remoisenet-Peyrard potential U<Subscript>RP</Subscript>(X,r), whose shape can be varied as a function...</subscript>

An atomic cluster moving along a solid surface can undergo dissipation of its translational energy through a direct mode, involving the coupling of the center-of-mass motion to thermal excitations of the substrate, and an indirect mode, due to damping of the internal motion of the cluster, to...

We investigate the structure and dynamics of the interface between two immiscible liquids in a three-dimensional disordered porous medium. We apply a phase-field model that includes explicitly disorder and discuss both spontaneous and forced imbibition. The structure of the interface is...
