Strong-field assisted extreme-ultraviolet lasing in atoms and molecules

Bredtmann, Timm; Patchkovskii, Serguei; Ivanov, Misha Yu

Using ab-initio simulations, we demonstrate amplification of extreme-ultraviolet (XUV) radiation during transient absorption in a high-harmonic generation type process using the example of the hydrogen atom. The strong IR ...

Sub-laser-cycle control of coupled electron–nuclear dynamics at a conical intersection

Richter, Maria; Bouakline, Foudhil; González-Vázquez, Jesús; Martínez-Fernández, Lara; Corral, Inés; Patchkovskii, Serguei; Morales, Felipe; Ivanov, Misha; Martín García, Fernando; Smirnova, Olga

Nonadiabatic processes play a fundamental role in the understanding of photochemical processes in excited polyatomic molecules. A particularly important example is that of radiationless electronic relaxation at conical ...

The role of the Kramers–Henneberger atom in the higher-order Kerr effect

Richter, Maria; Patchkovskii, Serguei; Morales, Felipe; Smirnova, Olga; Ivanov, Misha

We discuss the connection between strong-field ionization, saturation of the Kerr response and the formation of the Kramers–Henneberger (KH) atom and long-living excitations in intense infrared (IR) external fields. We ...
