Microscopic Quantum Friction
Quantum friction between two ground-state atoms arises from their relative motion coupled to dispersive response, appearing as odd-order terms in a velocity power series.

Claims
Our microscopic theory reveals that several properties of quantum friction obtained in specific settings -- such as the cubic dependence on velocity at zero temperature -- are indeed universal features already present at the atomic scale.
The requirement that odd-order terms survive only in the presence of an internal dissipation mechanism, together with the assumption that the derived force properties hold for arbitrary scattering trajectories without further model details.
Microscopic quantum friction emerges as odd-order velocity terms from atom-atom dispersive interactions, with first-order dominance at room temperature and universal features like zero-temperature cubic velocity dependence already present at atomic scale.
