- Before Schrodinger came up with this equation, the quantum physics community was unhappy with the mathematical formulation of the atomic model. The math was tedious and there was no room for visualizing or imagining a quantum system. These were just a few of the many problems that Schrodinger recognized.

Oct 24, 2024 · Essentially a wave equation, the Schrödinger equation describes the form of the probability waves (or wave functions [see de Broglie wave]) that govern the motion of small particles, and it specifies how these waves are altered by external influences.

The reason for the more intricate description necessary for microscopic pro cesses in comparison with macroscopic processes is simply the fact that these systems are so small that the interaction of the system with an eventual mea surement apparatus can no longer be neglected. It turns out this fact is not to overcome by choosing more and more soph...

In this section, we generalize the concepts we have learned in the previous sections. The goal here is to give a broader description of quantum mechanics in terms of wave functions that are solutions to the Schroedinger Equation. In classical mechanics the particle state is determined by its position and momentum and the state evolution is determin...

Thus we can freely change the basis in which we describe a certain physical problem. To account fully for this fact, we no longer wish to use wave me chanics, ie. express the wave function as a function in position space or in k-space. Instead we will utilize a vector in an abstract function space, i.e. a Hilbert space. In this way, we can formulat...
Oct 20, 2024 · Schrödinger’s wave equation does not satisfy the requirements of the special theory of relativity because it is based on a nonrelativistic expression for the kinetic energy (p 2 /2m e). Dirac showed that an electron has an additional quantum number m s .
The wave function as a complete description of the particle enables us to compute expected values of physical quantities of the particle when a cor-responding measurement is performed. The measurement results are real numbers, like the energy, o4 position or momentum the particle has in this state.
The Schrödinger equation is a partial differential equation that governs the wave function of a non-relativistic quantum-mechanical system. [1]: 1–2 Its discovery was a significant landmark in the development of quantum mechanics.
