Quantum friction is a non-equilibrium dispersion force, evoked by electromagnetic vacuum fluctuations, that hinders the relative motion of interacting, but non-touching, objects. Since quantum friction has not been confirmed experimentally yet, a profound understanding of the mechanisms at work is essential for the design of suitable setups. For instance, modifying the material or geometry of the system's constituents reshapes the spectrum of the vacuum field and therefore the characteristics of the interaction.
In this work we investigate the quantative impact of the chosen geometry on the quantum frictional force experienced by microscopic particles.
