强混合关联随机势Anderson模型的N体局域化

N-body localization for the Anderson model with strongly mixing correlated random potentials

Trésor Ekanga

摘要:

本文建立了具有关联但强混合随机外势的多粒子Anderson紧束缚模型的安德森局域化在谱指数和强动力学局域化下的解.结果是在多粒子哈密顿量谱的下边缘附近得到的。特别地,在极大范数下证明了本征函数的指数衰减,在Hilbert-Schmidt范数下证明了动力学局部化。证明需要随机外部随机过程的条件概率分布函数服从一致的log-Hölder连续性条件。

英文摘要:

This work establishes the Anderson localization in both the spectral exponential and the strong dynamical localization for the multi-particle Anderson tight-binding model with correlated but strongly mixing random external potential. The results are obtained near the lower edge of the spectrum of the multi-particle Hamiltonian. In particular, the exponential decay of the eigenfunctions is proved in the max-norm and the dynamical localization in the Hilbert-Schmidt norm. The proofs need the conditional probability distribution function of the random external stochastic processes to obey the uniform log-Hölder continuity condition.
