The paper of the VHEGEN program has just been accepted by Computer Physics Communications. VHEGEN stands for Vibronic Hamiltonian Expansion GENerator. It is a python code that allows you to key in a Jahn-Teller or a pseudo-Jahn-Teller problem and then returns the expansion formulas of the vibronic Hamiltonian matrix elements. It covers all bimodal problems in trigonal and tetragonal symmetries. Congratulations to Rob Lang and Riley Hickman, the two undergraduate researchers in our group that contributed to this work. They are now both graduate students at U of Toronto.
