20.09

Our rapid communication “Single vibronic level fluorescence spectra from Hagedorn wavepacket dynamics” was published in The Journal of Chemical Physics. Congrats to Dr. Tong, who just passed his public defense!

03.09

In their manuscript published on arXiv, Tong and our master student Maté showed that the combination of Hagedorn wavepacket and a local harmonic approximation of the potential provides an accurate single vibronic level fluorescence spectra of difluorocarbene.

21.08

Following his work on Hagedorn wavepacket, Tong proposed to combine the Hagedorn approach with a local harmonic approximation of the potential to capture anharmonic effects in single vibronic level fluorescence spectra. The manuscript is on arXiv!

15.05

Tong has been very busy and recently shared three manuscripts about Hagedorn wavepacket on arXiv! In the first one, he demonstrated the robustness of the method at evaluating single vibronic level fluorescence spectra of high-dimensional harmonic systems. In the second one, his methodology is applied to a realistic ab-initio model of the anthracene molecule. Finally, the last one discusses properties of Hagedorn wavepacket and presents algebraic recurrence expressions for the overlap between two Hagedorn functions with different Gaussian center.
