摘要: The aim of this paper is to revisit the calculation atom–surface quantum friction in field theory formulation put forward by Barton (2010 New J. Phys. 12 113045). We show that power dissipated into excitations and associated force depend on how atom boosted from being initially at rest a configuration which it moving constant velocity (v) parallel planar interface. In addition, we point out there subtle cancellation between one-photon part two-photon dissipating power, resulting leading order contribution frictional goes as v4. These results are also confirmed an alternative average radiation force, scales v3.
