A quasi-monoenergetic short time duration compact proton source for probing high energy density states of matter
J. I. Apiñaniz, S. Malko, R. Fedosejevs +15
We report on the development of a highly directional, narrow energy band, short time duration proton beam operating at high repetition rate, suitable for measurements of stopping p…
Towards an in situ, full-power gauge of the focal-volume intensity of petawatt-class lasers
C. Z. He, A. Longman, J. A. Pérez-Hernández +7
About 50 years ago, Sarachick and Schappert [Phys. Rev. D. 1, 2738 (1970)] showed that relativistic Thomson scattering leads to wavelength shifts that are proportional to the laser…
High-order harmonic generation driven by inhomogeneous plasmonics fields spatially bounded: influence on the cut-off law
E. Neyra, F. Videla, M. F. Ciappina +4
We study high-order harmonic generation (HHG) in model atoms driven by plasmonic-enhanced fields. These fields result from the illumination of plasmonic nanostructures by few-cycle…
Double-electron ionization driven by inhomogeneous fields
A. Chacón, L. Ortmann, F. Cucchietti +5
Electron-electron correlation effects play an instrumental role in our understanding of sequential (SDI) and non-sequential double ionization (NSDI) mechanisms. Here, we present a…
Emergence of a higher energy structure in strong field ionization with inhomogeneous electric fields
L. Ortmann, J. A. Pérez-Hernández, M. F. Ciappina +6
Studies of strong field ionization have historically relied on the strong field approximation, which neglects all spatial dependence in the forces experienced by the electron after…
Attosecond physics at the nanoscale
M. F. Ciappina, J. A. Pérez-Hernández, A. S. Landsman +22
Recently two emerging areas of research, attosecond and nanoscale physics, have started to come together. Attosecond physics deals with phenomena occurring when ultrashort laser pu…
