论文摘要
我们表明，具有自发损坏的翻译的均质全息模型的二元理论显示出具有远距离顺序的准晶体的几种独特特性（例如，不固定的电荷密度密度波）。这种解释表明，在这些系统的激发范围中观察到的纵向扩散模式是典型的Quasicrystals -Phason的扩散金石玻色子。此外，遵循这个想法，并在耗散系统中使用有效的田间理论形式主义作为戈德石模式，我们能够在这些全息模型中发现的普遍相位放松在少量的明确破裂来源（伪自发制度）的情况下。
We show that the field theories dual to the homogeneous holographic models with spontaneously broken translations display several distinctive properties of quasicrystals, aperiodic crystals with long-range order (e.g. incommensurate charge density waves). This interpretation suggests that the longitudinal diffusive mode, observed in the spectrum of excitations of these systems, is the diffusive Goldstone boson typical of quasicrystals -- the phason. Moreover, following this idea, and using the effective field theory formalism for Goldstone modes in dissipative systems, we are able to derive the universal phase relaxation found in these holographic models in presence of a small source of explicit breaking (pseudo-spontaneous regime).
