About this document
Quantum Mechanics: Energy Measurements and Operators by Gerson Misael is a document available to read on EtoBox.
This document contains the solution to a physics problem involving two observables A and B represented as matrices. The student first finds the eigenvalues and eigenvectors of A, which are λ1=2, λ2=1, λ3=1 and the corresponding eigenvectors v1, v2, v3. They then project the third eigenvector v3 of A onto the eigenvector w1 of B that corresponds to the eigenvalue -1. The probability of obtaining the values A=√2 and B=-1 is equal to the square of the absolute value of the projection, which is 1/4.
