QED theory of the multiphoton cascade transitions in atoms
QED theory the multiphoton cascade transitions atoms Atomic Physics
font style='font-size:12px;'>
2012/4/20
QED theory of multiphoton cascade transitions in atoms and ions is developed. This theory allows for the accurate description of the process important for astrophysical studies of the cosmological hyd...
Modeling core-hole screening in jellium clusters using density functional theory
Modeling core-hole screening jellium clusters density functional theory
font style='font-size:12px;'>
2012/2/28
The screening of a 2p core-hole in Na clusters is investigated using density functional theory applied to an extended jellium model with an all-electron atom in the center. The study is related to rec...
Theory of superfluidity and drag force in the one-dimensional Bose gas
Lieb-Liniger model, Tonks-Girardeau gas, Luttinger liquid, drag force, superfluidity, dynamical structure factor

2011/9/29
The one-dimensional Bose gas is an unusual superfluid. In contrast to higher spatial dimensions, the existence of non-classical rotational inertia is not directly linked to the dissipationless motion ...
Exact density functional theory with the density matrix renormalization group

High-order harmonic generation (HHG) by hydrogenlike atoms/ions in the uniform periodic electric field, formed by the two linearly polarized counterpropagating laser beams of relativistic intensities,...
Koopmans' theorem in statistical Hartree-Fock theory
Koopmans Hartree-Fock theory
font style='font-size:12px;'>
2011/8/30
In this short paper, the validity of Koopmans’ theorem in the Hartree-Fock theory at non-zero temperature (Hartree-Fock statistical theory) is investigated. It is shown that Koopmans’ theorem does not...
On the structure of the S-matrix in general boundary quantum field theory in curved space

2010/12/23
We use the general boundary formulation (GBF) of quantum field theory to compute the S-matrix for a general interacting scalar field in curved spacetime. This S-matrix is obtained as the asymptotic li...
