Backtranformed Jastrow
Posted: Sun Sep 25, 2022 12:34 pm
Hello everybody.
VMC is just Multiple integral brevity, written in bra–ket notation <φ(r)|H|φ(r)>/<φ(r)φ(r)> then backflow tranformation
(if it includes Jastrow factor) is change of variables and only requires the calculation of the determinant of backflow tranformation Jacobian matrix
opposed to when Jastrow factor is not backtranformed. Has anyone tried this kind of wfn? Are there any pitfalls here?
Best Vladimir
