Non-exponential and oscillatory decays in quantum mechanics The amplitudes Ac1 ≡ hc, E|H|1i are the matrix elements of the original Hamiltonian between an intrinsic state |1i and the channel state |c, Ei. The channel state is labeled here by the asymptotic energy E and all additional quantum number ...

Dual-path source engineering in integrated quantum optics
... (Received 14 July 2015; published 18 November 2015) Quantum optics in combination with integrated optical devices shows great promise for efficient manipulation of single photons. New physical concepts, however, can only be found when these fields truly merge and reciprocally enhance each other. Her ...
