Multiperiodic motion Bohr Sommerfeld quantization Bohr's correspondence principle provided a way to find the semiclassical quantization rule for a one degree of freedom system. Source: Internet
However, in the semiclassical expansion, one has a finite system of ODEs at any fixed order of ħ. The evolution equation of the Wigner function is also an infinite-order PDE. Source: Internet
Nevertheless, all semiclassical theories were refuted definitively in the 1970s and 1980s by photon-correlation experiments. Source: Internet
This is only reproduced in a more sophisticated semiclassical treatment like Sommerfeld's. Source: Internet
This ring seems to allow a closed time loop with stable wormholes when analyzed using semiclassical gravity, although without a full theory of quantum gravity it is uncertain whether the semiclassical approach is reliable in this case. Source: Internet
