We start with the decoherence coefficient of an inertial, polarizable par- ticle interacting with a thermal field [8, 9]: Λ th = 1 3(2π)3ϵ2 0c8 ∫ ∞ 0 dωω8|α0(ω)|2 (n(ω) + 1)n(ω)

Davies-Unruh Decoherence from Detailed Balance Remarkably, there is an analogy between the decoherence rateΛ DU derived above, the decoherence rate of an inertial detector cou
