Collinear helium under periodic driving: stabilization of the asymmetric stretch orbit
Peter Schlagheck, Detlef Pingel, Peter Schmelcher
The collinear eZe configuration of helium, with the electrons on opposite sides of the nucleus, is studied in the presence of an external electromagnetic (laser or microwave) field…

Nondispersive two-electron wave packets in driven helium
Peter Schlagheck, Andreas Buchleitner
We provide a detailed quantum treatment of the spectral characteristics and of the dynamics of nondispersive two-electron wave packets along the periodically driven, collinear froz…
