The Lande subtraction method has been widely used in Coulomb problems, but the momentum coordinate p∈(0,∞) is assumed. In past applications, a very large range of p was used for accuracy. We derive the supplementary formulation with p∈(0,pmax) at reasonably small pmax for practical calculations. With the recipe, accuracy of the hydrogenic eigenspectrum is dramatically improved compared to the ordinary Lande formula by the same momentum grids. We apply the present formulation to strong-field atomic above-threshold ionization andhigh-order harmonic generations. We demonstrate that the proposed momentum space method can be another practical theoretical tool for atomic strong-field problems in addition to the existing methods.

This paper proposes a polynomial-time algorithm for Minimum WdM/SONET Add/drop Multiplexer Problem (MAdM) on WdM directed fiber trees whether or not wavelength converters are used. It runs in time O(m2n), where n and m are the number of nodes of the tree and the number of the requests respectively. Incorporating T. Erlebach et al.'s work into the proposed algorithm, it also reaches the lower bound of the required wavelengths with greedy algorithms for the case without wavelength converters. Combined with some previous work, the algorithm reduces the number of required wavelengths greatly while using minimal number of AdMs for the case with limited wavelength converters. The experimental results show the minimal number of required AdMs on WdM directed fiber trees.
We describe a consistent splitting approach to the pressurestabilized Petrov-Galerkin finite element method for incompressible flow. The splitting leads to (almost) explicit predictor and corrector steps linked by an ...
