Re: Varmin and emin energies

When should one use emin rather than varmin (and vice versa)?

Thanks,

Cutoff lengths in the Jastrow factor

Can anyone advise me on how to choose the cutoff lengths of u, chi and f in the Jastrow factor for graphene? They don't seem to change much when I optimise them, but if I fix them at different values and optimise the other parameters I get significantly different VMC energies.

Thanks,

S.
