The position operator
In quantum mechanics, the canonical commutation relation is the fundamental relation between canonical conjugate quantities (quantities which are related by definition such that one is the Fourier transform of another). For example, between the position operator x and momentum operator px in the x direction of a point particle in one dimension, where [x , px] = x px − px x is the commutator of x and px , i is the imaginary unit, a… Webb1 sep. 2024 · You can reason to the average position of a particle in the ground state of the infinite potential well by just thinking about the shape of the wave function.

WebbThe product of two operators is de ned by operating with them on a function. Let the operators be A^ and B^, and let us operate on a function f(x) (one-dimensional for simplicity of notation). Then the expression A^B^f(x) is a new function. We can therefore say, by the de nition of operators, that A^B^ is an operator which we can denote by C^:
WebbOperator methods are very useful both for solving the Harmonic Oscillator problem and for any type of computation for the HO potential. The operators we develop will also be useful in quantizing the electromagnetic field. The Hamiltonian for the 1D Harmonic Oscillator looks like it could be written as the square of a operator.

Usually in QM we say that a wavefunction psi is an eigenfunction of some operator if that operator acting on psi gives eigenvalue * psi. The position operator is just "multiply by x". So any psi would seem to fit the above description of an eigenfunction of the position operator with eigenvalue x.
