Periodic points and transitivity on dendrites
Gerardo Acosta, Rodrigo Hernández-Gutiérrez, Issam Naghmouchi +1
We study relations between transitivity, mixing and periodic points on dendrites. We prove that when there is a point with dense orbit which is not an endpoint, then periodic point…
Opacity with Orwellian Observers and Intransitive Non-interference
John Mullins, Moez Yeddes
Opacity is a general behavioural security scheme flexible enough to account for several specific properties. Some secret set of behaviors of a system is opaque if a passive attacke…
Telegraph noise effects on two charge-qubits in double quantum dots
A. Ayachi, W. Ben Chouikha, S. Jaziri +1
We analyze theoretically the decoherence of two interacting electrons in a double self-assembled quantum dot due to a random telegraph noise. For this purpose we have examined the…
Tunable zero-energy transmission resonances in shifted graphene bilayer
A. Daboussi, L. Mandhour, J. N. Fuchs +1
A graphene bilayer is known to perfectly reflect normally incident electrons due to their chirality. This is similar to Klein tunneling, which, in a monolayer, is instead responsib…
Intertwining operator associated to the complex Dunkl operator of type
Fethi Bouzeffour, Sami Ghazouani
In this work, we consider the Dunkl complex reflection operators related to the group in the complex plane \begin{align*} T_i=\frac{\partial}{\partial z_i}+k_0\sum_{j\ne…
Stark widths of Ar III spectral lines in the atmospheres of subdwarf B stars
Rafik Hamdi, Nabil Ben Nessib, Sylvie Sahal-Bréchot +1
Using semiclassical perturbation approach in impact approximation, we have calculated Stark widths for 32 spectral lines of doubly charged argon (Ar III). Oscillator strengths are…
