abstract = "We first revisit the energy loss mechanism known as quantum vacuum
friction (QVF), clarifying some of its subtleties. Then we
investigate the observables that could easily differentiate QVF
from the classical magnetic dipole radiation for pulsars with
accurately measured braking indices (n). We show that this is
particularly the case for the time evolution of a pulsars magnetic
dipole direction (f\˙) and surface magnetic field (B\˙
0). As is well known in the context of the classic magnetic dipole
radiation, n < 3 would only be possible for positive ( \˙
\˙ B B 0 0 + f f tan ), which, for instance, leads to
B\˙ 0 > 0 (f\˙ > 0) when f (B0) is constant. On the
other hand, we show that QVF can result in very different
predictions with respect to those above. Finally, even if
B\˙ 0 has the same sign in both of the aforementioned models
for a pulsar, then, for a given f, we show that they give rise to
different associated timescales, which could be another way to
falsify QVF.",
