Almost Ballistic Transport for the Weakly Coupled Fibonacci Hamiltonian
David Damanik, Anton Gorodetski
We prove estimates for the transport exponents associated with the weakly coupled Fibonacci Hamiltonian. It follows in particular that the upper transport exponent …

Absolutely Continuous Convolutions of Singular Measures and an Application to the Square Fibonacci Hamiltonian
David Damanik, Anton Gorodetski, Boris Solomyak
We prove for the square Fibonacci Hamiltonian that the density of states measure is absolutely continuous for almost all pairs of small coupling constants. This is obtained from a…
