<div dir="ltr"><div>Hello CP2K community,</div><div><br></div><div>I am just following up on a question I had started on Github, realizing this is the proper venue for it.</div><div><br></div><div>I was reading a paper (Phys Rev Let. 120, 246801 (2018)) in which a
biased counter-electrode for an electrochemical cell was modeled using
Ne pseudoatoms with added fractional proton numbers and compensating fractional valence electrons. The working electrode was the metal of interest. This method resulted in an overall charge-neutral cell, but with the net amount of electrons rearranging across the electrodes. This then created a controllable bias across the cell, something otherwise not conventional in AIMD simulations. I had asked if this was possible in CP2K. <br></div><div><br></div><div>In the thread ( https://github.com/cp2k/cp2k/issues/839 ), the concept of applying positive and negative core correction to both sides of the cell was mentioned.</div><div><br></div><div>I wanted to follow up on this and ask - if positive and negative core corrections are applied to bias the electrodes, would there also be a net change in the number of electrons in each electrode, similar to what was done in the paper?</div><div><br></div><div>Thank you,</div><div>Anne<br></div></div>
