QED theory of the multiphoton cascade transitions in atoms
QED theory the multiphoton cascade transitions atoms Atomic Physics
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
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
density functional theory density matrix renormalization group electronic structure models
2011/8/17
Abstract: Combining density functional theory with controlled numerical methods for strongly correlated systems could greatly extend the range of both. We use the density matrix renormalization group ...
QED theory of the nuclear magnetic shielding in hydrogen-like ions
QED theory hydrogen-like ions
2011/9/6
The shielding of the nuclear magnetic moment by the bound electron in hydrogen-like ions is calculated ab initio with inclusion of relativistic, nuclear, and quantum electrodynamics (QED) effects. The...
Relativistic quantum theory of high harmonic generation on atoms/ions by strong laser fields

2011/9/1
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,...
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
the S-matrix quantum field theory
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...
Large-N reduction of SU(N) Yang-Mills theory with massive adjoint overlap fermions
1/N Expansion Eguchi-Kawai reduction Adjoint fermions
2011/1/13
We study four dimensional large-N SU(N) Yang-Mills theory coupled to adjoint overlap fermions on a single site lattice. Lattice simulations along with perturbation theory show that the bare quark mass...
