arXiv:2611.15198v1 Announce Type: new Abstract: The dissipaton theory was proposed more than a decade ago as a statistical quasiparticle theory for open quantum systems and was soon extended to nonlinear system-bath coupling. Although numerical results provided strong evidence for its validity, a rigorous mathematical foundation, particularly for nonlinear system-bath coupling, was established only recently. On this basis, we formulate the dissipaton-embedded quantum master equation for nonlinear system-bath coupling. This in-principle exact master equation describes the joint dynamics of the reduced system and all dissipaton degrees of freedom.
