Absolutely continuous spectrum for random SchrÃ¶dinger operators on the Fibonacci and similar Tree-strips
We consider cross products of finite graphs with a class of trees that have arbitrarily but finitely long line segments, such as the Fibonacci tree. Such cross products are called tree-strips. We prove that for small disorder random SchrÃ¶dinger operators on such tree-strips have purely absolutely continuous spectrum in a certain set.
