courses.physics.ucsd.eduAs is the case with most operators in quantum mechanics, we start from the clas-sical definition and make the transition to quantum mechanical operators via the standard substitution x → x and p → −i~∇. Be aware that I will not distinguish a classical quantity such as x from the corresponding quantum mechanical operator x.

Path Integrals in Quantum Mechanics
web.mit.eduQuantum mechanics is fully predictive [3] in the sense that initial conditions and knowledge of the potential occupied by the particle is enough to fully specify the state of the particle for all future times.1 In the early twentieth century, Erwin Schr¨odinger derived an equation specifies
Harmonic oscillator Notes on Quantum Mechanics
www.bu.eduThe harmonic oscillator is one of the most important model systems in quantum mechanics. An harmonic oscillator is a particle subject to a restoring force that is proportional to the displacement of the particle. In classical physics this means F =ma=m

ocw.mit.eduIn quantum mechanics the classical vectors lr, pl and Ll. become operators. More precisely, they give us triplets of operators: lr → (ˆx, y,ˆ zˆ), lp → ( ˆpx ,pˆy ,pˆz ), (1.3) Ll → (L. ˆ. x ,Lˆy ,Lˆz ). When we want more uniform notation, instead of x, y, and z labels we use 1, 2 and 3 labels:
