IT Security Eng. Linux admi / IT Risk Manager

I have been working in computer system since 2011, with expertise in Linux servers and networking. IT security is the topic of interest as you need to be precise 100 % and prevent or detect the issues, this suits fine to my scientific background and my way of working. I speak fluent Swedish and Spanish and have knowledge of Portuguese, Finnish and German. Lately, I work in the IT industry as IT Security Engineer for a large company in Germany.

Quantum Interference and Decoherence in Single-Molecule Junctions: How Vibrations Induce Electrical Current

America Physical Society - Phy. Rew. Letters.
Quantum interference and decoherence in single-molecule junctions is analyzed employing a nonequilibrium Green’s function approach. Electrons tunneling through quasidegenerate states of a molecular junction exhibit interference effects. We show that electronic-vibrational coupling, inherent to any molecular junction, strongly quenches such interference effects. This decoherence mechanism may cause significantly larger electrical currents and is particularly pronounced if the junction is vibrationally highly
