Dual kinetic balance approach to basis-set expansions for the dirac equation.
نویسندگان
چکیده
A new approach to finite basis sets for the Dirac equation is developed. It does not involve spurious states and improves the convergence properties of basis-set calculations. Efficiency of the method is demonstrated for finite basis sets constructed from B splines by calculating the one-loop self-energy correction for a hydrogenlike ion.

Application of the dual-kinetic-balance sets in the relativistic many-body problem of atomic structure
The dual-kinetic-balance (DKB) finite basis set method for solving the Dirac equation for hydrogen-like ions [V.M. Shabaev et al., Phys. Rev. Lett. 93 (2004) 130405] is extended to problems with a non-local spherically-symmetric Dirac–Hartree–Fock potential. We implement the DKB method using B-spline basis sets and compare its performance with the widely-employed approach of Notre Dame (ND) gro...
متن کاملThe effect of dual-task training on balance of elderly women: with the motor and cognitive approach
The aim of this study was to investigate the effectiveness of motor and cognitive dual-task training on dynamic balance of elderly women. For this purpose, 27 old women (aged 60 -82 years) from the old people center of Birjand city were selected randomly and divided into 3 groupd based on their TUG scores. The groups comprised of cognitive dual-task training, motor dual-task training and contro...
متن کاملAn embedding scheme for the Dirac equation
An embedding scheme is developed for the Dirac Hamiltonian H . Dividing space into regions I and II separated by surface S, an expression is derived for the expectation value of H which makes explicit reference to a trial function defined in I alone, with all details of region II replaced by an effective potential acting on S and which is related to the Green function of region II. Stationary s...
متن کاملSADDLE POINT VARIATIONAL METHOD FOR DIRAC CONFINEMENT
A saddle point variational (SPV ) method was applied to the Dirac equation as an example of a fully relativistic equation with both negative and positive energy solutions. The effect of the negative energy states was mitigated by maximizing the energy with respect to a relevant parameter while at the same time minimizing it with respect to another parameter in the wave function. The Cornell pot...
متن کاملKinetic Study of Fischer Tropsch Synthesis over co Precipitated Iron-Cerium Catalyst
The kinetic of Fischer-Tropsch synthesis over a co-precipitated Fe-Ce catalyst was investigated in a fixed bed micro reactor. Experimental conditions were varied as follow: reaction pressure 1-15bar, H¬¬¬2/CO feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°C. 4 models according to the Langmuir-Hinshelwood-Hougen-Watson (LHHW) type rate equation were der...
