We prove that the SchrÎ´dinger operator H= -~ + V(x)+F-x has ax purely absolutely continuous spectrum for arbitrary constant external field F, for a large class of potentials this result applies toâ€¦ (More)

Using a perturbative argument, we show that in any finite region containing the lowest transverse eigenmode, the spectrum of a periodically curved smooth Dirichlet tube in two or three dimensions isâ€¦ (More)

We develop a deterministic ab-initio model for the input-output relationship of a multipleinput multiple-output (MIMO) wireless channel, starting from the Maxwell equations combined with Ohmâ€™s Law.â€¦ (More)

We study the quantum dynamics generated by HSW = âˆ’ d dx2 +V âˆ’x with V a real periodic function of weak regularity. We prove that the continuous spectrum of HSW is never empty, and furthermore thatâ€¦ (More)

This paper studies the behavior of the sum-rate of outdoor multi-user multiple input multiple output systems, where a uniform linear array is utilized at the base station (BS), as the number of BSâ€¦ (More)

The theoretic capacity of a communication system constituted of several transmitting/receiving elements is determined by the singular values of its transfer matrix. Results based on an independentâ€¦ (More)

This is the second paper of the authors in a series concerned with the development of a deterministic model for the transfer matrix of a MIMO system. Starting from the Maxwell equations, we haveâ€¦ (More)

We investigate an electron in the plane interacting with the magnetic field due to an electric current forming a localized rotationally symmetric vortex. We show that independently of the vortexâ€¦ (More)

Abstract. We study the dynamics of a 1D Bloch electron subjected to a constant electric field. The periodic potential is supposed to be less singular than the Î´-like potential (Dirac comb). We give aâ€¦ (More)
