PhD Project: Applications of the stabilization method in molecular physics
Resume: We propose novel applications of the Stabilization Method (SM): the characterization of electronically excited states of neutral molecules and the identification of hidden resonances in electron-molecule scattering calculations performed with the Schwinger Multichannel method. The SM was first proposed by Hazi and Taylor [Phys. Rev. A 1970, 1 (1109)] as a technique to distinguish resonances from states that arise from the discretization of the continuum in bound-state calculations. Regarding electronically excited states of neutral molecules, by systematically varying the diffuseness of the basis set, our approach distinguishes valence, Rydberg, and mixed excited states without relying on the arbitrary criteria of traditional methods. In combination with the Schwinger Multichannel method, the SM was also employed to search for hidden shape resonances.
