Progress in miniaturized technology allows us to control physical systems at nanoscale with remarkable precision. Experimental advancements have sparked interest problems stochastic thermodynamics, typically concerning a time-dependent potential applied nanoparticle reach target stationary state given time minimal energy cost. We study this problem for particle subject thermal fluctuations regime that takes into account the effects of inertia, and, building on results previous work, we provide numerical method find optimal controls even non-Gaussian initial and final conditions, corresponding nonharmonic confinements. Although focus where driving is long compared characteristic relaxation times dynamics, protocol position distribution are qualitatively different from overdamped limit: particular, symmetry boundary which preserved absence turns out be broken underdamped regime. also show momentum mean tends constant value along trajectory, except close boundary, while evolution second moments highly nontrivial. Our support lower bound entropy production computed case tight adiabatic limit.
