Resonances in Fock Space: Optimization of a SASER device

We model the Fock space for the electronic resonant tunneling through a double barrier including the coherent effects of the electron-phonon interaction. The geometry is optimized to achieve the maximal optical phonon emission required by a SASER (ultrasound emitter) device.Comment: 4 pages, 3 figures, to be published in Proceedings of the VI Latin American Workshop on Nonlinear Phenomena, special issue of Physica
