A PARTICLE IN A POTENTIAL For the harmonic oscillator interacting with a reservoir Caldeira and Leggett [15] and Walls[40] provided an exact solution which shows a rich and intricate dependence on the parameters – too extensive to be discussed here. For weak coupling and high temperatures, however, the physics can be described by an equation of motion for the reduced density operator ρ(x, x , t) = x|ρs |x of the following form[41] (p.

Another example is the decay of an excited atom in state a which decays into the ground state b by spontaneous emission of a photon. The state of combined system “atom + radiation field” is |Ψ(t) = ca (t)|a, 0k + cb,k (t)|b, 1k . (58) k 7 This may also have far reaching consequences for the interpretation of the predicted proton–decay[25](c) (T T1/2 ≈ 1015 times the age of the universe). Ralph v. Baltz 48 From the Schrodinger equation we get two differential equations for ca , cb ¨ which can be solved in the Weisskopf–Wigner approximation[27, 29](Ch.

When the oscillation frequency ω0 of the TLS is small compared with the Debye–frequency, there is a universal lower bound on the decoherence rate Γ ω0 due to the atomic environment[36] x(t)x(0) = x20 e−Γt cos(ω0 t) , Γ= ω0 M 2 x20 ω05 ). coth( 3 2kB T 2π ρcs (82) ρ denotes the mass density, and cs the speed of sound. For a N H3 molecule (M = 3×10−23 g, ω0 = 1012 /s, x0 = 2×10−8 cm, ρ = 5g/cm3 , cs = 105 cm/s) Γ ≈ 1010 /s. For tunneling electrons the rate is much smaller.
