Singularity in Potential, Perturbation and Variational Methods
In this work, we carefully study the energy eigen-values and splitting of heavy quarkonia as there exist 1/r3 and δ3(~r) singular terms in the potential which make a direct numerical solution of the Schrödinger equation impossible. We compare the results obtained in terms of perturbation and variational methods with various treatments. It is well known that the interactions between heavy quarks...
متن کاملPerturbation and Variational Methods in Nonextensive Tsallis Statistics
A unified presentation of the perturbation and variational methods for the generalized statistical mechanics based on Tsallis entropy is given here. In the case of the variational method, the Bogoliubov inequality is generalized in a very natural way following the Feynman proof for the usual statistical mechanics. The inequality turns out to be form-invariant with respect to the entropic index ...
متن کاملSearch Costs in Quadtrees and Singularity Perturbation
Quadtrees constitute a classical data structure for storing and accessing collections of points in multidimensional space. It is proved that, in any dimension, the cost of a random search in a randomly grown quadtree has logarithmic mean and variance and is asymptotically distributed as a normal variable. The limit distribution property extends to quadtrees of all dimensions a result only known...

متن کاملThe electrostatic persistence length calculated from Monte Carlo, variational and perturbation methods
Monte Carlo simulations and variational calculations using a Gaussian ansatz are applied to a model consisting of a flexible linear polyelectrolyte chain as well as to an intrinsically stiff chain with up to 1000 charged monomers. Addition of salt is treated implicitly through a screened Coulomb potential for the electrostatic interactions. For the flexible model the electrostatic persistence l...
