<div>Dear CP2K developers,</div><div><br /></div><div>i want to investigate the interaction between an oxygen atom and a Au-111 surface. I encountered problems that my SCF calculations didn't converge and i'm quite certain that my problem is charge sloshing. Some calculations did eventually converge and i noticed that the partial charge of the oxygen was larger than expected. Thus, i want to include dipole correction in my SCF calculations but i can't converge these SCF calculations at all. Any recommendations are highly appreciated.</div><div><br /></div><div>Additionally, i have two questions about the input:</div><div>1) In FORCE_EVAL/DFT/SCF/MIXING: If i use the Broyden mixing method and i give the input a value for BETA (example input as below), is Kerker dampening/ preconditioning automatically activated? Or do i need to use the Kerker mixing mode?</div><div>Example Input:</div><div>&MIXING</div><div> METHOD BROYDEN_MIXING</div><div> ALPHA 0.01</div><div> BETA 1.5</div><div> NBUFFER 10</div><div>&END MIXING</div><div><br /></div><div>2) Apparently, i can optimize the BETA value by checking the mean of "
<span>eigenvalues of (default mixing * dielectric matrix)</span>". Any possibility i can print this information?</div><div><br /></div><div><br /></div>
<p></p>
