New required citation for publications using CASINO

Postby Neil Drummond » Wed Apr 22, 2020 12:27 pm

Dear All,

Hope you are safe and well during the coronavirus pandemic.

There is a new required citation for publications that use the CASINO software:

R. J. Needs, M. D. Towler, N. D. Drummond, P. Lopez Rios and J. R. Trail, Variational and diffusion quantum Monte Carlo calculations with the CASINO code, J. Chem. Phys. 152, 154106 (2020). URL: https://doi.org/10.1063/1.5144288

Please cite this in any publications that arise from use of CASINO. Thanks very much indeed!

Best wishes,

Neil.

Hi Neil,

Saw a pre-print on archive! Reads really nicely! Well done to you all.

Hope all are safe and well.

Hello Neil

This is an awesome article. I especially liked reading the part
V. FUTURE DIRECTIONS FOR QMC METHODS AND THE CASINO SOFTWARE

I could never understand why it is so fashionable to use FCIQMC because of its its exponential scaling , only medium-sized systems can be investigated, even though presence of the Jastrow factor decreases the importance
of those determinants in the CI wave function, which are mainly associated with dynamical correlation.
Even if we take a molecule that is mostly one-determinate, such as H2O, NH3, CH4, their single-determinant WFN has twice as many nodal pockets than for an exact nodal surface and somehow additional determinants should only change the topology of the nodal surface, probably add additional small cuts in it. I think that this can be done with BACKFLOW not with FCIQMC and I thought that Pablo López Ríos engaged in orbital-dependent BACKFLOW, but it turned out he was doing an even more interesting thing - tail-regression estimator (TRE) of atomic forces.

Also the Electron–electron pseudopotentials paragraph turned out to be interesting, although such an approach was new to me.

Thanks again to all the authors for such an interesting article.
In Soviet Russia Casino plays you.
