    • Macroscopic diagnostics of microscopic friction phenomena 

      Dahmen, Silvio Renato; Farkas, Zénó; Hinrichsen, Haye; Wolf, Dietrich Emil (2005) [Artigo de periódico]
      We show that the static friction force which must be overcome to render a sticking contact sliding is reduced if an external torque is also exerted. As a test system we study a planar disk lying on a horizontal flat surface. ...

    • Nonlinear friction of a damped dimer sliding on a periodic substrate 

      Goncalves, Sebastian; Kenkre, V. M.; Bishop, A. R. (2004) [Artigo de periódico]
      The nonlinear sliding friction of a dimer over a substrate is studied within a one-dimensional model, consisting of a vibrating dimer (two masses connected by a spring), internally damped, sliding over a sinusoidal potential. ...
