Rate of Convergence of the Configuration Interaction Model for the Helium Ground State
نویسنده
چکیده
The rate of convergence of a CI calculation on the ground state of the helium atom is rigorously derived under suitable assumptions on the regularity of the exact wavefunction. For bases consisting of all partial waves with angular momentum less than or equal to L, the large L asymptotic energies are found to obey the well-known formula EL − E = CL−3 + o(L−3), where C is an explicit constant defined in terms of the exact wavefunction.

A three-body model is devised to study differential and total cross sections for the excitation of helium atom under impact of energetic protons. The actual process is a four body one but in the present model the process is simplified into a three-body one. In this model, an electron of helium atom is assumed to be inactive and only one electron of the atom is active. Therefore, the active ele...

Motivated by recent experiments that detects Dzyaloshinskii-Moriya (DM) interaction in , we study the effects of DM interaction on magnetic orders of J1-J2 antiferromagnetic Heisenberg model. First, we find the classical phase diagram of the model using Luttinger-Tisza approximation. In this approximation, the classical phase diagram has two phases. For , the model has canted Neel and DM intera...

Among various cultural models, the dichotomy of static versus dynamic models has provided a fertile ground for research. Although a number of static models are suggested, the dominant trend in almost all static models is provided by Hofstede who focuses on cultural differences along four major dimensions (power distance, individualism, uncertainty avoidance, and masculinity) and reduces “the co...
متن کاملTwo Novel Learning Algorithms for CMAC Neural Network Based on Changeable Learning Rate
Cerebellar Model Articulation Controller Neural Network is a computational model of cerebellum which acts as a lookup table. The advantages of CMAC are fast learning convergence, and capability of mapping nonlinear functions due to its local generalization of weight updating, single structure and easy processing. In the training phase, the disadvantage of some CMAC models is unstable phenomenon...

Through the triple–alpha process practically all of the carbon in our universe is synthesized as the ash of helium burning in red giants. The triple–alpha process proceeds trough the ground state of Be and though the 02+–state in C. We investigate the dependence of 02+–state and the production of carbon as a function of the strength of the underlying nucleon–nucleon interaction. This is perform...
