Accuracy of the WKB approximation: the case of general quartic potential
Marko Vranicar, Marko Robnik
We analyse the accuracy of the approximate WKB quantization for the case of general one-dimensional quartic potential. In particular, we are interested in the validity of semiclass…

High order WKB prediction of the energy splitting in the symmetric double well potential
Marko Robnik, Luca Salasnich, Marko Vranicar
The accuracy of the WKB approximation when predicting the energy splitting of bound states in a double well potential is the main subject of this paper. The splitting of almost deg…
