Hi All,<div><br /></div><div>I had a theoretical question regarding the electric potential that is applied in CP2K.</div><div><br /></div><div>Let's say that a simulation box has a electric potential gradient applied to it in the +x-direction: electric potential gradient = 2X</div><div><br /></div><div>If you have positively charged ions (cations) and negatively charged ions (anions), which direction would they flow in relation to the electric potential gradient within CP2K?</div><div><br /></div><div>Do cations flow in the direction of the gradient (+x-direction) or against the gradient (-x-direction)?<br /></div><div><br /></div><div>In an isolated system, positively charged atoms would flow in the positive direction and negative atoms would flow in the negative direction toward a negatively charged region. However, in a system with PBC the region outside of the simulation box would be the opposite charge of the negative/positive ends of the main simulation box to "compensate". Just trying to wrap my head around this. Thanks!</div><div><br /></div><div>Thank you!</div><div>Best Regards,</div><div>Devyesh Rana</div>
