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 pla…
Local persistense and blocking in the two dimensional Blume-Capel Model
Roberto da Silva, Silvio R. Dahmen
In this letter we study the local persistence of the two--dimensional Blume-- Capel Model by extension of the concept of Glauber dynamics. We verify that for any value of the ratio…
