We studied the development of surface instabilities leading to the generation of multielectron bubbles (MEBs) in superfluid helium upon the application of a pulsed electric field. We found the statistical distribution of the charge of individual instabilities to be strongly dependent on the duration of the electric field pulse. The rate and probability of generation of these instabilities in re...

We study the role of intermediate excitations Rydberg states as an example Kuchiev's "atomic antenna" in above-threshold ionization xenon, particular their effect on coherence between spin-orbit-split ion. focus case a laser frequency close to resonant with spin-orbit splitting, where symmetry (parity) argument would preclude any being directly generated by strong-field ionization. Using ab ini...
