Delocalised states in a 1D diagonally disordered system
G. G. Kozlov
TL;DR
This paper demonstrates that in a one-dimensional diagonally disordered system with long-range interactions, some states remain delocalized, challenging the common belief that all such states are localized.
Contribution
It introduces a model with long-range exponential intersite interaction showing the existence of delocalized states in 1D disordered systems.
Findings
Some states are delocalized despite disorder
Long-range interactions can prevent localization in 1D systems
Challenges the traditional view of universal localization in 1D disordered systems
Abstract
1D diagonally disordered chain with Frenkel exciton and long range exponential intersite interaction is considered. It is shown that some states of this disordered system are delocalised contrary to the popular statement that all states in 1D disordered system are localised.
