The Quantum-Mechanical Model of an Atom02:45

The Quantum-Mechanical Model of an Atom

60.9K
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

State Space Representation

The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.
Consider an RLC circuit, a...

Valence Bond Theory and Hybridized Orbitals

32.3K
According to valence bond theory, a covalent bond results when: (1) an orbital on one atom overlaps an orbital on a second atom, and (2) the single electrons in each orbital combine to form an electron pair. The strength of a covalent bond depends on the extent of overlap of the orbitals involved. Maximum overlap is possible when the orbitals overlap on a direct line between the two nuclei.
A σ bond (single bond in a Lewis structure) is a covalent bond in which the electron density is...

Hybridization of Atomic Orbitals I

68.9K
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

    Area of Science:

    • Artificial Intelligence
    • Machine Learning
    • Computational Science

    Background:

    • Radial basis function networks (RBFNs) are crucial for approximation, but their performance depends heavily on center and radius selection.
    • Traditional statistical methods for RBFN parameterization may lack adaptability to diverse data distributions.
    • Quantum clustering (QC) offers a robust approach to identifying data structures by drawing from quantum mechanics principles.

    • To integrate the data concentration discovery inherent in quantum clustering into a neural network framework.
    • To address the limitations of traditional RBFNs in adapting to complex data structures.

    Main Methods:

    • Developed the quantum local potential function network (QLPFN) model, inspired by quantum clustering.
    • Constructed wave and potential functions within the QLPFN architecture to analyze data concentration.
    • Implemented automatic generation of local potential functions from data subsets using subspace division procedures.
