随机耦合系数对退相干的影响

The effect of random coupling coefficients on decoherence

Mario Castagnino, Sebastian Fortin, Olimpia Lombardi

摘要:

本文的目的是分析相互作用哈密顿量中耦合系数的随机性对退相干的影响。通过对自旋浴模型的计算机模拟研究,我们发现这种随机性大大提高了退相干的“效率”,其物理意义值得考虑。

英文摘要:

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.
