| Abstract: | The Casimir friction problem can be dealt with in a simplified way by considering two
harmonic oscillators moving with constant relative velocity. Recently we calculated the
energy dissipation ΔE for such a case Europhys. Lett. 91,
60003 (2010); Eur. Phys. J. D 61, 335 (2011)]. A recent study of Barton New
J. Phys. 12, 113044 (2010)] seemingly leads to a different result for the
dissipation. If such a discrepancy really were true, it would imply a delicate difficulty
for the basic theory of Casimir friction. In the present note we show that the expressions
for ΔE are in fact physically equivalent, at
T = 0. |
