The Quantum-Mechanical Model of an Atom02:45

The Quantum-Mechanical Model of an Atom

43.1K
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.

The Bohr Model

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as...

The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells.

First Law: Particles in One-dimensional Equilibrium

7.1K
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...

Equilibrium Conditions for a Particle

1.4K
When an object is in equilibrium, it is either at rest or moving with a constant velocity. There are two types of equilibrium: static and dynamic. Static equilibrium occurs when an object is at rest, while dynamic equilibrium occurs when an object is moving with a constant velocity. In both cases, there must be a balance of forces acting on the object.
To understand the concept of equilibrium, let us first consider the forces acting on an object. When different forces act on an object, they can...

Fermi Level Dynamics01:12

Fermi Level Dynamics

336
The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.

This summary is machine-generated.

This study introduces a chiral SU(15) gauge theory where quarks and leptons are prebaryon bound states. This model explains three generations and prevents rapid proton decay, suggesting potential unification of fundamental forces.

Area of Science:

  • Particle Physics
  • Quantum Field Theory
  • Theoretical Physics

Background:

  • The Standard Model describes fundamental particles and forces but has limitations.
  • Understanding the origin of particle generations and mass is a key challenge.
  • A unified theory of fundamental forces remains an open area of research.

Purpose of the Study:

  • To propose a novel chiral SU(15) gauge theory.
  • To investigate the nature of quarks and leptons as bound states of preons.
  • To explore implications for particle generations, Higgs fields, and force unification.

Main Methods:

  • Development of a chiral SU(15) gauge theory framework.
  • Analysis of preon dynamics and bound state formation.
  • Investigation of implications for Standard Model charges and fermion generations.

Main Results:

  • Quarks and leptons are identified as "prebaryons" (bound states of massless preons).
  • Preon charges naturally yield three generations of quarks and leptons.
  • Bound states of two prebaryons can function as Higgs fields under specific chiral dynamics assumptions.
  • The theory suggests potential unification of Quantum Chromodynamics (QCD) and electroweak groups above the confining scale (Λpre).
  • The SU(15) symmetry inherently prevents rapid proton decay.

Conclusions:

  • The proposed chiral SU(15) gauge theory offers a potential framework for understanding fundamental particle properties.
  • The model provides a mechanism for generating particle generations and Higgs fields from more fundamental constituents.
  • It suggests a path towards Grand Unification and addresses the proton decay problem inherent in some theories.
