A matrix-valued point interactions model
Hakim Boumaza
We study a matrix-valued Schrödinger operator with random point interactions. We prove the absence of absolutely continuous spectrum for this operator by proving that away from a d…

Positivity of Lyapunov exponents for Anderson-type models on two coupled strings
Hakim Boumaza, Günter Stolz
We study two models of Anderson-type random operators on two deterministically coupled continuous strings. Each model is associated with independent, identically distributed four-b…
