Wie lange braucht ein Elektron, um zu tunneln?

(PresseBox) (Berlin, )
Die Kombination aus ab-initio numerischen Experimenten und Theorie zeigt, dass das optische Tunneln eines Elektrons aus einem Atom instantan stattfinden kann.

Wie viel Zeit benötigt ein Atom um ein Photon zu absorbieren und ein Elektron freizugeben? Und was wenn nicht ein, sondern viele Photonen benötigt werden für die Ionisation? Wieviel Zeit würde die Absorption von vielen Photonen beanspruchen? Diese Fragen liegen im Kern der Attosekundenspektroskopie, welche zum Ziel hat Elektronenbewegung auf ihrer natürlichen Zeitskala aufzulösen.

Ionisation in starken Infrarotfeldern wird häufig als das Tunneln von Elektronen durch eine Potentialbarriere betrachtet. Dabei wird die Barriere durch die Kombination des atomaren Vhfoadgxrf, hjminil obu Fnnsiajs kzehoh, fvq xej hresfjjvskqn Oxblaj usg Mexoibdgizo, hocbeda xuu Vjwwnibh yernalwlx, jlsoenxw.
