Researchers from Yeshiva University Discuss Findings in Entropy (Entropy Content During Nanometric Stick-Slip Motion)

August 12, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Entropy. According to news reporting originating from New York City, New York, by VerticalNews correspondents, research stated, "To explore the existence of self-organization during friction, this paper considers the motion of all atoms in a systems consisting of an Atomic Force Microscope metal tip sliding on a metal slab. The tip and the slab are set in relative motion with constant velocity."

Our news editors obtained a quote from the research from Yeshiva University, "The vibrations of individual atoms with respect to that relative motion are obtained explicitly using Molecular Dynamics with Embedded Atom Method potentials. First, we obtain signatures of Self Organized Criticality in that the stick-slip jump force probability densities are power laws with exponents in the range (0.5, 1.5) for aluminum and copper. Second, we characterize the dynamical attractor by the entropy content of the overall atomic jittering."

According to the news editors, the research concluded: "We find that in all cases, friction minimizes the entropy and thus makes a strong case for self-organization."
