Pulse length effects in long wavelength driven non-sequential double ionization
H. Jiang, M. Mandrysz, A. Sanchez +8
We present a joint experimental and theoretical study of non-sequential double ionization (NSDI) in argon driven by a 3100-nm laser source. The correlated photoelectron momentum di…
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…
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…
High-order harmonic generation from Rydberg atoms driven by plasmonic-enhanced laser fields
Y. Tikman, I. Yavuz, M. F. Ciappina +3
We theoretically investigate high-order harmonic generation (HHG) in Rydberg atoms driven by spatially inhomogeneous laser fields, induced, for instance, by plasmonic enhancement.…
Controlling electron localization of H by intense plasmon-enhanced laser fields
I. Yavuz, M. F. Ciappina, A. Chacón +2
We present a theoretical study of the wave packet dynamics of the H molecular ion in plasmon-enhanced laser fields. Such fields may be produced, for instance, when metallic n…
Signatures of double-electron re-combination in high-order harmonic generation driven by spatially inhomogeneous fields
A. Chacón, M. F. Ciappina, M. Lewenstein
We present theoretical studies of high-order harmonic generation (HHG) driven by plasmonic fields in two-electron atomic systems. Comparing the two-active electron and single-activ…
Above-threshold ionization and photoelectron spectra in atomic systems driven by strong laser fields
Noslen Suárez, Alexis Chacón, Marcelo Ciappina +2
Above-threshold ionization (ATI) results from strong field laser-matter interaction and it is one of the fundamental processes that may be used to extract electron structural and d…
Numerical studies of light-matter interaction driven by plasmonic fields: the velocity gauge
A. Chacón, M. Lewenstein, M. F. Ciappina
Theoretical approaches to strong field phenomena driven by plasmonic fields are based on the length gauge formulation of the laser-matter coupling. From the theoretical viewpoint i…
Quantum-orbit analysis of high-order harmonic generation by resonant plasmon field enhancement
T. Shaaran, M. F. Ciappina, M. Lewenstein
We perform a detailed analysis of high-order harmonic generation (HHG) in atoms within the strong field approximation (SFA) by considering spatially inhomogeneous monochromatic las…
High-order harmonic generation from inhomogeneous fields
M. F. Ciappina, J. Biegert, R. Quidant +1
We present theoretical studies of high-order harmonic generation (HHG) produced by non-homogeneous fields as resulting from the illumination of plasmonic nanostructures with a shor…
