Quantum Anharmonic Oscillator - Emperor2011 - 05-19-2026 Quantum Anharmonic Oscillator | 12.55 MB Title: Quantum Anharmonic Oscillator Author: Alexander Turbiner Language: English | 307 Pages | ISBN: 9811270457 Description: Quartic anharmonic oscillator with potential V(x)= x² + g²x⁴ was the first non-exactly-solvable problem tackled by the newly-written Schrödinger equation in 1926. Since that time thousands of articles have been published on the subject, mostly about the domain of small g² (weak coupling regime), although physics corresponds to g² ~ 1, and they were mostly about energies. This book is focused on studying eigenfunctions as a primary object for any g². Perturbation theory in g² for the logarithm of the wavefunction is matched to the true semiclassical expansion in powers of ℏ: it leads to locally-highly-accurate, uniform approximation valid for any g²∈[0,∞) for eigenfunctions and even more accurate results for eigenvalues.
