Global Energy Solutions for Normalized Linear Stochastic Schr{ö}dinger Equations
Théo Hérouard
Source abstract
In this paper, we study nonlinear Schr{ö}dinger equations arising in the study of Markovian open quantum systems. These equations are derived from the normalization of linear stochastic Schr{ö}dinger equations. First, we prove the global well-posedness of the linear equation in the energy space, which is less regular than the usual space for this equation. Then, we show the indistinguishability of solutions to the nonlinear SPDE under a relaxation of the usual monotonicity assumption. Finally, by proving the pathwise uniqueness and normalizing the solutions to the linear equation, we are able to prove the well-posedness of solutions to the required class of nonlinear stochastic equations.
