Gaps, Errors and Corrections of the Schrödinger Equation

Abstract

The “quantum” world, within the framework of which “outstanding” scientific discoveries are being made now, is built on initially laid nonsense. Quantum theory was initially built on incorrect adjustment by Schrödinger of two-dimensional “solutions” of the One-dimensional harmonic oscillator equation. These are the consequences of this fitting and “excited minds.” This is the reason why quantum mechanics is not necessary to UNDERSTAND, but it is necessary to ACCEPT. But they accepted and canonized, as is shown in this work, non-physical, rough, approximate solutions. And it is on the basis of these solutions that electron orbitals, widely used in fundamental and applied science, are constructed. So the “Terrible Secret” of the theorists is that in fact without having a basic model they are exclusively engaged in fitting Schrödinger’ssolutions.

Planck-Einstein Quantization

Stanislav Ordin

The Schrödinger equation describes the basic physical models in a very contradictory way. And its canonization, which gives a catastrophic divergence of the energy of electronic levels with an increase in the mass of an atom, in principle, stalled the development of science. Nevertheless, it allowed, albeit roughly, to systematize and describe many phenomena of the microworld, primarily the hydrogen atom. And approximate descriptions of many “quantum” effects were obtained, but with the use of numerous adjustable parameters. So the bottom line from the century of development of quantum theory (QT) is, in fact, the development of some quantum mechanical methods.

Quantum Theory

Sven Larsson

Toward the end of the nineteenth century, it became clear that some experiments cannot be explained on the basis of known physics, now referred to as classical physics. In 1900, Max Planck was able to correctly describe the distribution of blackbody radiation energy as a function of wavelength λ or frequency ν = c/λ. He had to accept the existence of energy packets (quanta) with energy E = hν. A few years later, Albert Einstein found that this unexpected relation between energy and frequency is also necessary in order to understand photoemission from metallic surfaces. A decade later, Niels Bohr arrived at the correct equation for the electronic spectrum of the hydrogen atom by applying “quantum conditions” on the motion of the electron around the nucleus and the Planck’s relation E = hν on the energy difference between the energy levels (1916). A decade later, Heisenberg, Born, and Jordan introduced “quantum mechanics” and de Broglie and Schrödinger (1925-1926) introduced “wave mechanics.”

Quantum Theory Comes in Waves and Particles

Walter A. Harrison

Certainly there is no unique answer to Frank Wilczek’s question, “What Is Quantum Theory?” (Physics Today, June 2000, page 11). I was not certain that a pragmatic answer, which I proposed for a course in applied quantum mechanics, 1 1. W. A. Harrison, Applied Quantum Mechanics, World Scientific, River Edge, N.J. (2000). would be sustainable for the entire course, but it seems that it was. That answer was the assertion that everything is both a particle and a wave, and that everything else would follow from that one assertion. Planck’s constant arose when the velocity of a wave (the derivative of the frequency with respect to wavenumber) was equated to the velocity of a particle (the derivative of the energy with respect to momentum), so that energy is proportional to frequency and momentum to wavenumber, with the same proportionality constant ħ. When Hamiltonian mechanics was introduced, “everything” became anything that can be described by such mechanics, or anything that satisfies a wave equation. Quantum theory does not say what nature gives, only how to predict the behavior of what is given. If nature serves up particles with half-integral angular momentum, the wavefunction that describes them must go into its negative when they are interchanged, and they therefore obey the Pauli principle.Such principles, which historically arose as independent conjectures, now follow from the one assertion. It is a matter of seeing how this peculiar assertion can turn out to be absolutely true.The relation between quantum theory and the physical world was seen as follows: Quantum theory tells what future scenarios are consistent with some initial information, and what the relative probability of each scenario is. Quantum theory cannot tell more than that, but neither can any other theory.My pragmatic approach may not satisfy everyone’s philosophical needs. But the aim of an applied quantum course is to see how to use the theory and to introduce the many approximations that have made the theory accessible to physicists and engineers. If some basic consequences are difficult to accept, the problem must lie with the initial assertion from which the consequences follow.REFERENCESection:ChooseTop of pageREFERENCE <<1. W. A.

100 years of quantum mechanics: The months that changed physics

Milan R. Pantić

A hundred years ago, physics underwent one of its most dramatic transformations - a paradigm shift that fundamentally changed our understanding of nature. Over the course of several revolutionary months in 1925 and early 1926, quantum mechanics emerged as a new, foundational theory of the microscopic world. With the publication of key papers by Werner Heisenberg and Erwin Schrödinger, the theoretical framework was established that radically redefined our perception of physical reality. These works demonstrated that atoms and subatomic particles do not obey the laws of classical mechanics, but instead follow entirely new, quantum laws. Born in those intense months, quantum mechanics became one of the cornerstones of modern physics and a lasting source of inspiration in both theoretical and applied sciences. This paradigmatic shift opened new avenues of research and laid the groundwork for scientific discoveries that continue to shape our understanding of nature today. This paper is dedicated to those pivotal historical moments - the months in which science made one of its deepest leaps and most consequential strides in comprehending the world.

Theoretical Background

Anne‐Marie Sapse

Inadequate descriptions of atoms and molecules by the methods of classical physics led researchers to propose new ways to describe physical reality, giving birth to a totally new science, quantum mechanics. The methods of quantum mechanics are based on the introduction of a wave function, whose physical meaning is related to the probability of finding a certain particle, at a certain time in a volume element, positioned between x and x + dx in the x = direction, between y and y + dy in the y = direction, and between z and z + dz in the z = direction at certain time t. This wave function Ψ satisfies the Schrödinger equation, $$ \left( { - \frac{{{\hbar ^2}}}{{2m}}{\nabla ^2} + v} \right)\Psi = {\rm E}\Psi,\hbar = \frac{h}{{2\pi }}, $$ or for short, HΨ = EΨ, where H, the Hamiltonian operator, is defined by the expression $$ H = - \frac{{{\hbar ^2}}}{{2m}}{\nabla ^2} + V; $$ h is Planck’s constant; ∇2 is the sum of the partial second derivatives with respect to x, y, and z; m is the mass of the particle; and V is the potential energy of the system. The Hamiltonian H represents the quantum equivalent of the sum of the kinetic energy and potential energy, with V being the potential energy operator and $$ \frac{{ - {\hbar ^2}}}{{2m}}{\nabla ^2} $$ the kinetic energy operator. Finally, E is the total energy of the system and is a number, not an operator.

Relativistic Approximations for Quantization and Harmony in the Schrödinger Equation, and Why Mechanics Is Quantized

Antony J. Bourdillon

The initial purpose is to add two physical origins for the outstandingly clear mathematical description that Dirac has left in his Principles of Quantum Mechanics. The first is the “internal motion” in the wave function of the electron that is now expressed through dispersion dynamics; the second is the physical origin for mathematical quantization. Bohr’s model for the hydrogen atom was “the greatest single step in the development of the theory of atomic structure.” It leads to the Schrodinger equation which is non-relativistic, but which conveniently equates together momentum and electrostatic potential in a representation containing mixed powers. Firstly, we show how the equation is expansible to approximate relativistic form by applying solutions for the dilation of time in special relativity, and for the contraction of space. The adaptation is to invariant “harmonic events” that are digitally quantized. Secondly, the internal motion of the electron is described by a stable wave packet that implies wave-particle duality. The duality includes uncertainty that is precisely described with some variance from Heisenberg’s axiomatic limit. Harmonic orbital wave functions are self-constructive. This is the physical origin of quantization.
