Strong-field ionization of atoms and molecules: The two-term saddle point method

Autor: Kjeldsen, Thomas Kim, Madsen, Lars Bojer

Publikováno v: Phys. Rev. A 74, 023407 (2006)

We derive an analytical formula for the ionization rate of neutral atoms and molecules in a strong monochromatic field. Our model is based on the strong-field approximation with transition amplitudes calculated by an extended saddle point method. We

Vibrational excitation of diatomic molecular ions in strong-field ionization of diatomic molecules

Autor: Kjeldsen, Thomas Kim, Madsen, Lars Bojer

Publikováno v: Phys. Rev. Lett. 95, 073004 (2005)

A model based on the strong-field and Born-Oppenheimer approximations qualitatively describes the distribution over vibrational states formed in a diatomic molecular ion following ionization of the neutral molecule by intense laser pulses. Good agree

In collaboration with members of a Ju/’Hoansi community in Namibia,we have co-created a gesture-controlled VR application of a huntingstory, as told by an elder in the village, demonstrated in the fieldby an elder and youth, as well as 3D models an

Juice appearance is important to consumers, so digital juice with a slider that varies a production parameter or changes juice content is useful. It is however challenging to render juice with scattering particles quickly and accurately. As a case st
