Quantum Mechanics from a Heisenberg‐Type Equality
Quantum Mechanics from a Heisenberg‐Type Equality
The usual Heisenberg uncertainty relation, ΔX ΔP ≥ h̄/2, may be replaced by an exact equality for suitably chosen measures of position and momentum uncertainty, which is valid for all wave functions. This exact uncertainty relation, δX ΔPnc ≡ h̄/2, can be generalised to other pairs of conjugate observables such …
