Question on Brueckner #51

Closed vvp-nsk closed 8 months ago

vvp-nsk commented 8 months ago

Hej!

I am sorry to bother you again but would like to clarify one issue. If one combines Brueckner orbital rotation with the DCSD ansatz, would it effectively result in the so-called BDCD approach?

Thank you in advance!

With best regards, Victor

Not a bother -- yes, that is correct. I believe that I have compared BDCD against literature values when I was adding DCD and DCSD, though I didn't write a unit test for this. Let me know if you try it and the results don't seem to match expectation.
