The ground electronic state of CS: the potential curve and associated Born-Oppenheimer rovibrational spectrum
Horacio Olivares-Pilon, Alexander V Turbiner
Basics of the Born-Oppenheimer (B-O) approximation are reviewed. Assuming the domain of applicability of B-O approximation is limited to 4 significant digits (s.d.) in energy spect…
SUSY Quantum Mechanics, (non)-Analyticity and Phase Transitions
Alexander V Turbiner
It is shown by analyzing the Schrödinger equation that discontinuities in the coupling constant can occur in both the energies and the eigenfunctions. Surprisingly, those disc…
Towards the "puzzle" of Chromium dimer Cr: predicting the Born-Oppenheimer rovibrational spectrum
Horacio Olivares-Pilón, Daniel Aguilar-Díaz, Alexander V. Turbiner
The experimentally-observed non-trivial electronic structure of the Cr dimer has made the calculation of its potential energy curve a theoretical challenge in the last decades.…
