This paper deals with optimal impulsive control problems whose states are functions of bounded variation and impulsive controls are regular vector measures. The problem under consideration has multipoint state constraints. Examples of such problems may be found in mechanics, quantum electronics, robotics, ecology, economics, etc. Sufficient global optimality conditions involving certain sets of...

The Charge transport in desoxyribonucleic acid (DNA) is being intensively investigated in view of its biological implications in damage and repair, protein bonding, and envisioned integration in future (bio)electronics or DNA-based chips. Notwithstanding, despite sustained efforts to unveil the nature and range of charge transfer in these biomolecules, present knowledge lacks stable foundations...

Semiconductor nanostructures are potential building blocks for many applications in photonics, electronics, physics, and life sciences. They are also a good candidate to study quantum mechanics and related novel phenomena, based on the dimensionality and the size reduction. Among various nanostructures, one-dimensional (1-D) III-V nanostructures grown on Si substrates have received a lot of att...

Some guidelines for the comparison of different quantum key distribution experiments are proposed. An improved « plug & play » interferometric system allowing fast key exchange is then introduced. Self-alignment and compensation of birefringence remain. Original electronics implementing the BB84 protocol and allowing user-friendly operation is presented. Key creation with 0.1 photon per pulse a...

In an earlier publication, preliminary observations of the generation of electrical currents were reported in GaAs and low-temperature-grown GaAs (LT-GaAs) at 295 K using quantum interference control of singleand two-photon band–band absorption of 1.55and 0.775m ultrashort optical pulses. Timeintegrated currents were measured via charge collection in a metal–semiconductor–metal (MSM) electrode ...
