不含小参数的重整化到定域化

Renormalization to localization without a small parameter

A. G. Kutlin, I. M. Khaymovich

摘要:

研究了随机分布的d维粒子模型中的波函数局域化性质,该模型中各向同性跳跃势仅依赖于粒子间的欧几里德距离。由于该模型的通用性,通常称为欧几里德随机矩阵模型,它自然地出现在各种物理背景下,如振动模式,人工原子系统,液体和玻璃,超冷气体和光子局域化现象的研究。我们推广了已知的Burin-Levitov重整化群的方法,制定了普遍的条件,充分的本地化在这样的模型和检查之间的波函数空间衰减的欧氏随机矩阵和双折射不变的长程晶格模型与对角无序的惊人的等价性。

英文摘要:

We study the wave function localization properties in a d-dimensional model of randomly spaced particles with isotropic hopping potential depending solely on Euclidean interparticle distances. Due to the generality of this model usually called the Euclidean random matrix model, it arises naturally in various physical contexts such as studies of vibrational modes, artificial atomic systems, liquids and glasses, ultracold gases and photon localization phenomena. We generalize the known Burin-Levitov renormalization group approach, formulate universal conditions sufficient for localization in such models and inspect a striking equivalence of the wave function spatial decay between Euclidean random matrices and translation-invariant long-range lattice models with a diagonal disorder.
