Semiclassical quantization (source code)

= Semiclassical quantization
{title2=$I/\hbar\gg1$}

<Semiclassical quantization> uses classical trajectories and actions to approximate quantum states in a regime where relevant actions are large compared with $\hbar$. Phase consistency on a periodic orbit leads to <Bohr-Sommerfeld quantization>. Soliton <collective coordinates> can be quantized this way, while fluctuations supply additional corrections to the leading classical <mass>.
