Quantization Of LC Circuit =============================== :Date: 1 August 2019 What is the problem ? ------------------------ Derivation ------------- **Step 1** Write down the Hamiltonian, and find correspondence: .. math:: \begin{align*} & H(I,Q) = {1\over 2}LI^2 + {1\over 2}{Q^2\over C}\\ & H(p,q) = {p^2\over 2m} + {1\over 2}m\omega^2 q^2\\ \end{align*} .. math:: \begin{align*} & L\leftrightarrow m & C \leftrightarrow {1\over m\omega^2}\\ & I\leftrightarrow {p\over m} & Q \leftrightarrow q \end{align*} **Step 2** Results from Quantum-Harmonic-Oscillator then follows
