Asymptotic-Hamiltonian conjecture. The Hamiltonian $H_{{\rm S},\lambda,\beta}$ absorbs the leading-order correction to the non-interacting dynamics

Consider a quantum system coupled to a bath, with system-bath coupling controlling both decoherence and the noise induced in the classical dynamics. Let $D$ denote the diffusion te…

Linear decoherence light-cone conjecture. This light cone is linear for

The authors consider an environment containing $10^{23}$ spins and argue that gravitational and quantum-mechanical limitations in measurement lead to loss of coherence in quantum e…

Let the Wigner function represent the evolving density operator of a quantum Markovian system, and consider the intermediate stage between the initial loss of quantum coherence and…
