Reconstruction of a single-active-electron potential from electron momentum distribution produced by strong-field ionization using optimization technique

N. I. Shvetsov-Shilovski

We present a method for retrieving of single-active electron potential in an atom or molecule from a given momentum distribution of photoelectrons ionized by a strong laser field.…

Finite temperature spectrum at the symmetry-breaking linear-zigzag transition

Jan Kiethe, Lars Timm, Haggai Landa +3

We investigate the normal mode spectrum of a trapped ion chain at the symmetry-breaking linear to zigzag transition and at finite temperatures. For this purpose we modulate the amp…

Motional heating of spatially extended ion crystals

D. Kalincev, L. S. Dreissen, A. P. Kulosa +3

We study heating of motional modes of a single ion and of extended ion crystals trapped in a linear radio frequency (rf) Paul trap with a precision of …

The Heidelberg compact electron beam ion traps

P. Micke, S. Kühn, L. Buchauer +16

Electron beam ion traps (EBIT) are ideal tools for both production and study of highly charged ions (HCI). In order to reduce their construction, maintenance, and operation costs w…

Trapping, Shaping and Isolating of Ion Coulomb Crystals via State-selective Optical Potentials

Pascal Weckesser, Fabian Thielemann, Daniel Hoenig +3

For conventional ion traps, the trapping potential is close to independent of the electronic state, providing confinement for ions dependent primarily on their charge-to-mass ratio…
