Stick-slip motion and onset of sliding for five-layer soft lubricant  (Nl=5)


Stick-slip motion. Left panel: starting from an annealed configuration (pdb, rsm, xyz, Java MV) for vdrive= 0.03 (run "t02");  Right panel: after a set of runs with  vdrive= 0.1, 0.3, 1, 0.3, 0.1, 0.03, and finally 0.01 (run "t09").

Movies for atomic motion (left: "t02" mov 24.9 Mb, avi, gif;  right: "t09" mov 26.6 Mb, avi, gif)

Structure factor for the run "t02" (LS (α1-:-2), starting from the annealed configuration; uses sf-t02.mov 4.0 Mb, or see sf-t02.avi or sf-t02.gif)

 

Structure factor for the run "t09" (LoLS (β1-:-4); uses sf-t09.mov 3.6 Mb, or also see sf-t09.avi or sf-t09.gif)

 

 


Onset of sliding starting from the annealed (α1) and stick (α2) configurations during stick-slip motion for vdrive= 0.03, when slips correspond to the LS regime, and from stick configurations (β1,β2,β3,β4) during stick-slip motion for vdrive= 0.01, when slips correspond to the LoLS motion

 

Movies for atomic motion. Left panel shows a side view, middle panel shows evolution of (averaged) local potential energy (in green), right panel shows velocities (in red) in the lubricant layer.

 

(α1) Starting from an annealed configuration ("x01" pdb, rsm, xyz, Java MV; movies: mov 1.35 Mb, avi, gif; layer by layer)

 

(α2) Starting from the stick configuration ("x02" pdb, rsm, xyz, Java MV; movies: mov 1.19 Mb, avi, gif; layer by layer)

 

(β1) Starting from a stick configuration ("y01" pdb, rsm, xyz, Java MV; movies: mov 0.99 Mb, avi, gif; layer by layer)

 

(β2) Starting from a stick configuration ("y02" pdb, rsm, xyz, Java MV; movies: mov 4.16 Mb, avi, gif; layer by layer)

 

(β3) Starting from a stick configuration ("y03" pdb, rsm, xyz, Java MV; movies: mov 1.2 Mb, avi, gif; layer by layer)

 

(β4) Starting from a stick configuration ("y04" pdb, rsm, xyz, Java MV; movies: mov 2.56 Mb, avi, gif; layer by layer)
