We investigate the evolution of the quantum state for a free particle placed into a random external potential of white-noise type. The master equation for the density matrix is derived by means of path integral method. We propose an equivalent stochastic process where the wavefunction satisfies a nonlinear Schr\"odinger equation except for random moments at which it shows orthogonal jumps. The relation of our work to the usual theory of quantum noise and damping is briefly discussed.

    The paper introduces a general framework extending piecewise-deterministic unravelings to arbitrary trace-nonpreserving master equations requiring only positivity and Hermiticity of the dynamics.
