Re: Orbital optimization of the electron-hole system

Hi Pablo

We believe that it is not the case. We have made several tests with different number of walkers without any sucesss (when we use Mahan orbital). For plane wave it seems ok. Could you make a short run test with your imputs using latest casino version considering mahan orbital ?

Re: Orbital optimization of the electron-hole system

Dear Pablo We would like to have your helping to understand what's going on with my QMC calculations for the hole-doped electron gas system using the CASINO code (latest version ). First of all, I would like to reproduce your data provided on http://dx.doi.org/10.17863/CAM.565 . Using exactly your i...

Orbital optimization of the electron-hole system

Hello Casino users, I have tried to reproduce some results of the the article "Trion formation in a two-dimensional hole-doped electron gas" present in the list of papers published using the Casino program. I have done the optimization of the variational parameters to the backflow transfor...

calculate the condensate fraction of excitons

Hello the Casino users I am struggling to calculate the condensate fraction of excitons in an electron-hole system using DMC. My question is: This is very time consuming to calculate? I did the following run test: 58 electron, 58 holes, Nwalkers=10 and Nstep=100 the time to performe one block took t...
