Hamiltonin operaattori, lyhyesti hamiltoni, vastaa kvanttimekaniikassa systeemin kokonaisenergiaoperaattoria. Hamiltonin operaattori siirtää myös tilavektoria ajassa eteenpäin Schrödingerin yhtälön mukaisesti. Klassisessa mekaniikassa Hamiltonin operaattoria vastaa Hamiltonin funktio, joka kuvaa mekaanista systeemiä paikka- ja liikemäärämuuttujilla. Ne muodostavat perustan Hamiltonin me… WebSep 10, 2024 · The Hamiltonian operator for a free non-relativistic particle looks like H ^ = p ^ 2 2 m = − ℏ 2 2 m ∇ 2. In polar coordinates, the Laplacian expands to H ^ = − ℏ 2 2 m ( 1 r ∂ ∂ r ( r ∂ ∂ r) + 1 r 2 ∂ 2 ∂ θ 2). The radial and angular momentum operators are p ^ r = ℏ i ( ∂ ∂ r + 1 2 r) p ^ θ = ℏ i 1 r ∂ ∂ θ.
