Self-adjointness and spectrum of Stark operators on finite intervals
H. Najar, M. Zahri
In this paper, we study self-adjointness and spectrum of operators of the form is ca…
A quantum waveguide with Aharonov Bohm magnetic field
H. Najar, M. Raissi
In a previous study \cite{n} we investigate the bound states of the Hamiltonian describing a quantum particle living on three dimensional straight strip of width . We impose the…
Lifshitz tails for matrix-valued Anderson models
Hakim Boumaza, Hatem Najar
This paper is devoted to the study of Lifshitz tails for a continuous matrix-valued Anderson-type model acting on $L^2(\R^d)\otimes \C^{D}$, for arbitrary and $D\ge…
Spectral and localization properties of the Dirichlet wave guide with two concentric Neumann discs
Hatem Najar, Oleg Olendski
Bound states of the Hamiltonian describing a quantum particle living on three dimensional straight strip of width are investigated. We impose the Neumann boundary condition on…
Lifshitz tails for a percolation model in the continuum
Werner Kirsch, Hatem Najar
In this paper we study Lifshitz tails for continuous Laplacian in a continuous site percolation situation. By this we mean that we delete a random set from and conside…
About a result of S.M. Kozlov
Hatem Najar
We give an alternative proof and improve upon a result of S.M. Kozlov \cite{ko}. It deals with the asymptotic of the integrated density of states of the acoustic operator $\display…
