Spectral analysis of the clinometric data at the Phlegraean Fields from 1992 to 1998
Spectral analysis Phlegraean Fields clinometric data
2015/9/29
Ground deformation is one of the most important precursors for volcanic eruptions. In this respect, the surveillance of volcanoes has greatly benifited from the continuous recording of clinometric dat...
Solving the inverse problem of high numerical aperture focusing using Slepian-type vector fields
High numerical aperture focusing Vector diffraction theory Inverse problem Slepian’s concentration problem
2012/5/29
A technique using vector Slepian harmonics and multipole fields is presented for a general treatment of the inverse problem of high numerical aperture focusing. A prescribed intensity distribution or ...
Optical dipole force on ladder-like three-level atomic systems driven by chirped few-cycle-pulse laser fields
Optical dipole force ladder-like three-level atomic systems chirped few-cycle-pulse laser fields Optics
2012/5/17
We report a study on the optical dipole force in a ladder like three level atomic systems in the context of coherent population transfer with the chirped few-cycle-pulse laser fields. The phenomenon o...
Dynamic of rescattering-electron wave packets in strong and short-wavelength laser fields: Roles of Coulomb potential and excited states
scattering-electron wave packets in strong short-wavelength laser fields Coulomb potential excited states
2014/5/28
We investigate the high-order harmonic generation of atoms and molecules exposed in strong and shortwavelength (shorter than 800 nm) laser fields. Our simulations show that the electronic rescattering...
Forcibly driven coherent soft phonons in GeTe with intense THz-rate pump fields

Theoretical Study of the Soft Optic Mode Scattering Relaxor Ferroelectric Depolarizing Fields
2010/11/19
We analyze scattering of the transverse optic modes by spherically symmetric Polarized Nano Regions (PNR) in the paraelectric phase of relaxor ferroelectrics. Calculations have done in the frame of me...
Time-resolved analysis of strong-field induced plasmon oscillations in metal clusters by spectral interferometry with few-cycle laser fields
Time-resolved analysis strong-field induced plasmon oscillations metal clusters

We propose a scheme for ultrafast real-time imaging of laser-induced collective electron oscillations (Mie plasmons) in gas phase metal clusters by interferometrically stable scanning of two intense ...
Direct Ionization Desorption of Fullerene by Intense Femtosecond Laser Fields
C60 Solid Femtosecond Ionization
2009/6/1
We investigated the direct ionization and desorption of solid C60 by the irradiation of femtosecond nonresonant (neutral and cationic states) pulses at 1.4 µm. We concluded that ion desorption i...
