Hydrogen atoms in circularly polarized microwave fields: Near-integrability and ionization
(American Physical Society, 1995-08-01)We have recently found that the hydrogen atom in a circularly polarized (CP) microwave field possesses an approximate dynamical symmetry and its bounded motion can be well described by a three-dimensional integrable (but ... -
High-order perturbation expansion of non-Hermitian Floquet theory for multiphoton and above-threshold ionization processes
(American Physical Society, 1999-12-14)A high-order perturbation theory is presented for efficient and accurate computation of multiphoton and above-threshold ionization cross sections of atoms and molecules in weak to medium strength laser fields. The procedure ... -
High-order harmonic generation in atomic hydrogen at 248 nm: Dipole-moment versus acceleration spectrum
(American Physical Society, 1992-12-01)We present a study of the high-order harmonic-generation (HG) spectra of atomic hydrogen at 248 nm based on the Fourier transform of the expectation values of the induced dipole moment and acceleration. The calculations ... -
Generation of circularly polarized multiple high-order harmonic emission from two-color crossed laser beams
(American Physical Society, 1998-10-01)We present a scheme for the production of circularly polarized multiple high-order harmonic generation (HHG). The proposed experimental setup involves the use of two-color laser fields, consisting of a circularly polarized ... -

(American Physical Society, 1986-03-01)A Floquet-Liouville supermatrix (FLSM) approach is presented for nonperturbative treatment of the time development of the density-matrix operator of atoms and molecules exposed to intense polychromatic fields. By extending ... -
Floquet formulation for the investigation of multiphoton quantum interference in a superconducting qubit driven by a strong ac field
(American Physical Society, 2009-03-03)We present a Floquet treatment of multiphoton quantum interference in a strongly driven superconducting flux qubit. The periodically time-dependent Schrödinger equation can be reduced to an equivalent time-independent ... -

(Society of Photo-optical Instrumentation Engineers, 2006-02-23)A novel subpicosecond pulse radiolysis experimental system has been developed in Terawatt Ultrafast High Field Facility (TUHFF) at Argonne National Laboratory. TUHFF houses a 20 TW Ti:sapphire laser system that generates ... -
Infrared spectroscopic signatures of (NH4)2SO4 aerosols
(American Geophysical Union, 1996-08-20)Ammonium sulfate particles in air with average diameters ranging from 0.1 to 0.5-μm have been generated by atomizing aqueous solutions of (NH4)2SO4 of various concentrations at ambient temperatures and pressures. The ... -

(American Geophysical Union, 1999-09-20)Sodium chloride droplets with a median diameter of ∼0.4 μm were generated in the laboratory by atomizing an aqueous solution of NaCl under ambient conditions. Infrared extinction spectra of the aerosols under controlled ... -
Initial state‐selected reaction probabilities for OH+H2→H+H2O and photodetachment intensities for HOH− 2

(American Institute of Physics, 1995-03-01)We present a new approach for the direct (and correct) calculation of thermal rate constantsk(T) (‘‘direct’’ meaning that one avoids having to solve the state‐to‐state reactive scattering problem, and ‘‘correct’’ meaning ... -
