Superlubric-Locked Transition of Twist Grain Boundaries in 3D Crystals
Jin Wang, Erio Tosatti
Properties of twist grain boundaries (TGB), long known structurally but not tribologically, are simulated under sliding and load, with Au(111) our test case. The load-free TGB moir…

Can Neural Networks Learn Nanoscale Friction?
Mahboubeh Shabani, Andrea Silva, Franco Pellegrini +6
Current nanofriction experiments on crystals, both tip-on-surface and surface-on-surface, provide force traces as their sole output, typically exhibiting atomic size stick-slip osc…

Universal Moiré Buckling of Freestanding 2D Bilayers
Jin Wang, Erio Tosatti
The physics of membranes, a classic subject, acquires new momentum from two-dimensional (2D) materials multilayers. This work reports the surprising results emerged during a theore…
