Conservation laws for Electron Vortices in Strong-Field Ionisation
Yuxin Kang, Emilio Pisanty, Marcelo Ciappina +3
We investigate twisted electrons with a well defined orbital angular momentum, which have been ionised via a strong laser field. By formulating a new variant of the well-known stro…

Manipulating Twisted Electrons in Strong-Field Ionization
A. S. Maxwell, G. S. J. Armstrong, M. F. Ciappina +5
We investigate the discrete orbital angular momentum (OAM) of photoelectrons freed in strongfield ionization. We use these `twisted' electrons to provide an alternative interpretat…
