#### Derivation of schrodinger equation

## How was the Schrodinger equation derived?

In quantum mechanics, the analogue of Newton’s law is Schrödinger’s equation. Using these postulates, Schrödinger’s equation can be derived from the fact that the time-evolution operator must be unitary, and must therefore be generated by the exponential of a self-adjoint operator, which is the quantum Hamiltonian.

## What is Schrodinger equation?

i = imaginary unit, Ψ = time-dependent wavefunction, h^{2} is h-bar, V(x) = potential and H^ = Hamiltonian operator. Also Read: Quantum Mechanical Model of Atom. Time-independent Schrödinger equation in compressed form can be expressed as; OR. Time-independent-Schrödinger-nonrelativistic-equation.

## Can principles of quantum mechanics derive Schrodinger wave equation?

As Samim said, you cannot derive the Schrödinger equation from some deeper set of principles. It was built on de Broglie’s idea of matter waves and the analogy with the relation between photons and wave optics. This is the energy-momentum relation for photons.

## Why is there an I in the Schrodinger equation?

The imaginary constant i appears in the original Schroedinger article (I) for positive values of the energy, which therefore are discarded by Schrödinger, who wants real eigenvalues and requires negative energy.

## Is the cat alive or dead?

In simple terms, Schrödinger stated that if you place a cat and something that could kill the cat (a radioactive atom) in a box and sealed it, you would not know if the cat was dead or alive until you opened the box, so that until the box was opened, the cat was (in a sense) both “dead and alive”.

## What is Schrodinger’s cat name?

In Wild Arms 3, the character of Shady the Cat, owned by Maya Schrödinger, is based on Schrödinger’s cat, and is claustrophobic as a result of the “experiment”.

## What are the applications of Schrodinger equation?

Schrödinger’s equation offers a simple way to find the previous Zeeman–Lorentz triplet. This proves once more the broad range of applications of this equation for the correct interpretation of various physical phenomena such as the Zeeman effect.

## Who derived the wave equation?

Leonhard Euler
