Non-equilibrium molecular dynamics simulations, of crucial importance insliding friction, are hampered by arbitrariness and uncertainties in theremoval of the frictionally generated Joule heat. Building upon generalpre-existing formulation, we implement a fully microscopic dissipation approachwhich, based on a parameter-free, non-Markovian, stochastic dynamics, absorbsJoule heat equivalently to a semi-infinite solid and harmonic substrate. As atest case, we investigate the stick-slip friction of a slider over atwo-dimensional Lennard-Jones solid, comparing our virtually exact frictionalresults with approximate ones from commonly adopted dissipation schemes.Remarkably, the exact results can be closely reproduced by a standard Langevindissipation scheme, once its parameters are determined according to a generaland self-standing variational procedure.
