Wavefunctions in Momentum and Position Basis - Operators and …

In quantum mechanics, the position operator is the operator that corresponds to the position observable of a particle. When the position operator is considered with a wide enough domain (e.g. the space of tempered distributions), its eigenvalues are the possible position vectors of the particle. In one … Visa mer In one dimension – for a particle confined into a straight line – the square modulus In other terms, if – at a certain instant of time – the particle is in the state represented by a square integrable wave function Visa mer The generalisation to three dimensions is straightforward. The space-time wavefunction is now $${\displaystyle \psi (\mathbf {r} ,t)}$$ and the expectation value … Visa mer • Position and momentum space • Momentum operator • Translation operator (quantum mechanics) Visa mer In the above definition, as the careful reader can immediately remark, does not exist any clear specification of domain and co-domain for the position operator (in the case of a particle … Visa mer The eigenfunctions of the position operator (on the space of tempered distributions), represented in position space, are Dirac delta functions.
