Quantizing Schrodinger Field continued

Classical Action: Started with a classical system described by the action: � = ∫ � � ∫ � 3 �   � S = ∫ d t ∫ d 3 x L where � = � ∗ ( � ℏ ∂ � − � ^ ) � L = ψ ∗ ( i ℏ ∂ t ​ − H ^ ) ψ . Schrödinger equation arises from the classical action. Expansion and Eigenfunctions: Expanded � ψ in terms of eigenfunctions � � u n ​ of the Hamiltonian � ^ H ^ : � = ∑ � � � � � ψ = ∑ n ​ a n ​ u n ​ . � � u n ​ satisfies � ^ � � = � � � � H ^ u n ​ = e n ​ u n ​ . Quantization: � � a n ​ and � � ∗ a n ∗ ​ were taken as generalized coordinates and momenta. Replaced functions with operators, imposing commutation relations: [ � � , � � ∗ ] = � � � [ a n ​ , a m ∗ ​ ] = δ mn ​ .
