Description:
Author(s): Emanuele Panizon, Giuseppe E. Santoro, Erio Tosatti, Gabriele Riva, and Nicola Manini Friction between sliding objects is a phenomenon so ubiquitous that it is easily forgotten how few of its microscopic details are properly understood. To gain new insight into the dynamical mechanism of sliding dissipation, the authors investigate a minimal model of a rigid slider traveling over a harmonic substrate. With the analytical tools of linear response theory, the authors obtain an expression for the dynamical friction that depends on known static physical quantities. This result sheds new light on the physical intertwining between dissipation and the phononic degrees of freedom of the substrate. [Phys. Rev. B 97, 104104] Published Thu Mar 15, 2018
