Abstract content <br> &nbsp; (Max 300 words)

We present a stochastic wave-function unravelling of the generalized Lindblad master equation using correlated states, that is a combination of the system state vectors and the environment population. We apply the time-convolutionless projection operator method (TCL) to a two-state system, a qubit, coupled to an environment consisting of two energy bands which are both populated. Monte Carlo wave-function simulations based on the unravelling of the master equation are compared to the TCL solution and the exact solution of the Schrodinger equation. A typical quantum trajectory and average time evolution of the state vector on the Bloch sphere is also presented.
