We　systematically　derive　the　quantum　generalized　nonlinear　Langevin　equation　using　Morozov＇s　projection　operator　method.　This　approach　extends　the　linear　Mori-Zwanzig　projection　operator　technique,　allowing　for　the　inclusion　of　nonlinear　interactions　among　macroscopic　modes.　Additionally,　we　obtain　the　quantum　generalized　Fokker-Planck　equation　within　the　Heisenberg　picture,　which　is　consistent　with　Morozov＇s　original　formulation.　These　equations　are　fundamentally　significant　in　nonequilibrium　statistical　physics,　particularly　in　scenarios　characterized　by　enhanced　fluctuations,　such　as　anomalous　transport　phenomena　near　critical　points.　The　quantum　nature　of　the　derived　generalized　Langevin　and　Fokker-Planck　equations　is　anticipated　to　provide　a　more　detailed　description　than　their　classical　equivalents.　Specifically,　the　noise　kernel　in　the　quantum　generalized　Langevin　equation　is　multiplicative,　which　broadens　the　applicability　beyond　Gaussian　approximations.　Given　specific　interactions,　these　equations　are　expected　to　be　instrumental　in　investigating　critical　transport　phenomena.　　©　2024　American　Physical　Society.
