强无序非线性链的热化

Thermalization of Strongly Disordered Nonlinear Chains

Tsampikos Kottos, Boris Shapiro

摘要:

本文从理论和数值两方面研究了由离散非线性薛定谔方程描述的系统在强无序极限下的热化。我们表明,在无序势中引入相关性,同时保持“有效”无序固定(由波包动力学的局域化性质测量),强烈促进热化过程,并导致与每个站点相关的概率范数的标准巨正则分布

英文摘要:

Thermalization of systems described by the discrete non-linear Schrödinger equation, in the strong disorder limit, is investigated both theoretically and numerically. We show that introducing correlations in the disorder potential, while keeping the "effective" disorder fixed (as measured by the localization properties of wavepacket dynamics), strongly facilitate the thermalization process and lead to a standard grand canonical distribution of the probability norms associated to each site
