LC plasma frequency ω_LC = 1/√(LC) from bilinear-form diagonalisation; ℏω·(a†a+1/2)

LC plasma frequency from bilinear-form diagonalisation. From framework F8, the LC-Hamiltonian bilinear form H_LC = Φ²/(2L) + Q²/(2C) has principal axes given by the (a, a†) basis defined by Φ = √(ℏZ₀/2)·(a + a†), Q = −i·√(ℏ/(2Z₀))·(a − a†)…
