We prove exponentially small estimates on the oo-diagonal terms of the scattering matrix associated to two-state semiclassical Schrr odinger Hamiltonians. Our method is based on phase space tunneling estimates and a splitting of the operator by means of Toeplitz-type phase space cut-oo operators.

Inference on large-scale models is of great interest in modern science. Examples include deterministic simulators of fluid dynamics to recover the source of a pollutant, and stochastic agent-based simulators to infer features of consumer behaviour. When computational constraints prohibit model evaluation at all but a small ensemble of parameter settings, exact inference is infeasible. In such c...
