Re: Regarding 1D QMC using external potential

Dear Sir, We are trying to download Developer's version to add a new external potential to examine the property of 1d quantum wire. But we are unable to download. It asks for username and password. When we fill , it says Authentication fails. While registring we have not opted for Developer's versio...

Re: Regarding 1D QMC using external potential

Dear Neil, Thank you for promt reply. It seems we could not clear other questions, which we restate again: (ii) how different confining potential, V(x), such as trapping through an square well potential or other trapping potential can be used in the program? How does the program will modifies for tr...

Re: Regarding 1D QMC using external potential

Dear Sir, We tried to run the input file you sent. It seems that it is for infinitely thin wire. But could not understand following points: (i) how the input file changes for Harmonic wire model ( mentioned in Lee and Neil Drummond, PRB 83, 2011). (ii) how different V(x_ij ) has been used in the pro...

Regarding 1D QMC using external potential

Dear Sir,

I did not find any example for 1D quantum wire in the presence of external potential as done in the paper Lee and Neil Drummond, PRB 83, 2011.
We wish to start with this model and study the correlation energy.

Thanks and best regards,
Pathak
