Quantum dynamical study of Si(100) surface-mounted, STM-driven switches at the atomic and molecular scale
… Si(100) surface (Grey et al., 1996). The second system examines the conformational switching of single 1,5-cyclooctadiene molecules chemisorbed on the Si(100) surface (Nacci et al., 2008). The temporal dynamics are provided by the propagation of the density matrix in time via an according set of …

Selective excitation of adsorbate vibrations on dissipative surfaces
… has been simulated within the framework of open-system density matrix theory. Not only potential-mediated, inter-mode coupling poses an obstacle to selective excitation but also the coupling of the adsorbate ("system") modes to the electronic and phononic degrees of freedom of the surface …

Vibrationally enhanced associative photodesorption of H2 (D2) from Ru(0001) : quantum and classical approaches
… representations are employed within open-system density matrix theory. The time evolution of the desorption process is studied using a two-mode reduced dimensionality model with one vibrational coordinate and one translational coordinate of the adsorbate. The ground and excited …
