Medium propagation effects in high harmonic generation of Ar and N
Cheng Jin, Anh-Thu Le, C. D. Lin
We report theoretical calculations of high harmonic generation (HHG) by intense infrared lasers in atomic and molecular targets taking into account the macroscopic propagation of b…
Separation of Target Structure and Medium Propagation Effects in High-Harmonic Generation
Cheng Jin, Hans Jakob Worner, V. Tosa +6
We calculate high-harmonic generation (HHG) by intense infrared lasers in atoms and molecules with the inclusion of macroscopic propagation of the harmonics in the gas medium. We s…
Universal three-body physics at finite energy near Feshbach resonances
Yujun Wang, B. D. Esry
We find that universal three-body physics extends beyond the threshold regime to non-zero energies. For ultracold atomic gases with a negative two-body -wave scattering length n…
Cold three-body collisions in hydrogen-hydrogen-alkali atomic system
Yujun Wang, J. P. D'Incao, B. D. Esry
We have studied hydrogen-hydrogen-alkali three-body systems in the adiabatic hyperspherical representation. For the spin-stretched case, there exists a single H molecular state…
Polarization and ellipticity of high-order harmonics from aligned molecules generated by linearly polarized intense laser pulses
Anh-Thu Le, R. R. Lucchese, C. D. Lin
We present theoretical calculations for polarization and ellipticity of high-order harmonics from aligned N, CO, and O molecules generated by linearly polarized lasers.…
New determination of structure parameters in strong field tunneling ionization theory of molecules
Song-Feng Zhao, Cheng Jin, Anh-Thu Le +2
In the strong field molecular tunneling ionization theory of Tong et al. [Phys. Rev. A 66, 033402 (2002)], the ionization rate depends on the asymptotic wavefunction of the molecul…
