The effect of random coupling coefficients on decoherence
arXiv:0907.2729 · doi:10.1142/S0217732310032196
Abstract
The aim of this letter is to analyze the effect on decoherence of the randomness of the coupling coefficients involved in the interaction Hamiltonian. By studying the spin-bath model with computer simulations, we show that such randomness greatly improves the "efficiency" of decoherence and, then, its physical meaning deserves to be considered.
