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…
Principal frequency of an ultrashort laser pulse
Enrique G. Neyra, Pablo Vaveliuk, Emilio Pisanty +3
We introduce an alternative definition of the main frequency of an ultrashort laser pulse, the principal frequency . This parameter is complementary to the most accepted and w…
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…
Control of attosecond light polarization in two-color bi-circular fields
Álvaro Jiménez-Galán, Nick Zhavoronkov, David Ayuso +6
We develop theoretically and confirm both numerically and experimentally a comprehensive analytical model which describes the propensity rules in the emission of circularly polariz…
Above-threshold ionization (ATI) in multicenter molecules: the role of the initial state
N. Suárez, A. Chacón, E. Pisanty +6
A possible route to extract electronic and nuclear dynamics from molecular targets with attosecond temporal and nanometer spatial resolution is to employ recolliding electrons as `…
High harmonic interferometry of the Lorentz force in strong mid-infrared laser fields
Emilio Pisanty, Daniel D. Hickstein, Benjamin R. Galloway +4
The interaction of intense mid-infrared laser fields with atoms and molecules leads to a range of new opportunities, from the production of bright, coherent radiation in the soft x…
Spin conservation in high-order-harmonic generation using bicircular fields
Emilio Pisanty, Misha Ivanov, Suren Sukiasyan
We present an alternative theoretical model for a recent experiment [A.Fleischer et al., Nature Photon. 8, 543 (2014)] which used bichromatic, counter-rotating high intensity laser…
Momentum transfers in correlation-assisted tunnelling
Emilio Pisanty, Misha Ivanov
We consider correlation-assisted tunnel ionization of a small molecule by an intense low-frequency laser pulse. In this mechanism, the departing electron excites the state of the i…
