<div>Following the conversation of this thread: https://groups.google.com/g/cp2k/c/fmZX3_2kivc</div><div><br></div><div>I did a parameter sweep of my system using FIST dynamics, and determined that<br></div><div>GAMMA = 0.35</div><div>NOISY_GAMMA=1e-5 </div><div><br></div><div>yields best thermostat stability in my system. The paper mentioned in above conversation however uses slightly different terminology of Gamma_L (Langevin friction) and Gamma_D(intrinsic friction). And their values are rather low (1e-8 for Gamma_D and 0 for Gamma_L ). I would like to understand</div><div><br></div><div>1. How are GAMMA, NOISY_GAMMA, and SHADOW_GAMMA are related to Gamma_L and Gamma_D?</div><div>2. Does the value I got (0.3 and 1e-5) pass the initial smell test? Or do they look non-physical (I mostly use Nose thermostat but needs to use Langevin for this study for replicating a paper)? </div><div><br></div><div>Thank you<br></div>
