Noncontact friction: Role of phonon damping and its nonuniversality
Noncontact friction: Role of phonon damping and its nonuniversality
While obtaining theoretical predictions for dissipation during sliding motion is a difficult task, one regime that allows for analytical results is the so-called noncontact regime, where a probe is weakly interacting with the surface over which it moves. Studying this regime for a model crystal, we extend previously obtained analytical …
