[QE-users] Looking for systems that are difficult to converge with SCF

[John McFarland]

Dear all,


I'm trying to find systems that are difficult to converge with SCF.  This includes systems where the energy will fluctuate with SCF iterations, or systems that converge to a local minimum or excited state.  Any info on where I could find or produce such systems, or even actual input files, would be most welcome.


Best regards,


John McFarland
