The editors assembled thirteen contributions from leading scholars to present a unified voice, standardize terminology, and assess the state-of-the-art. There are three main clusters of articles, corresponding to the classical stages of the planning process: strategic, tactical, and operational. These three clusters are further subdivided into five parts which correspond to the main phases of the railway network planning process: network assessment, capacity planning, timetabling, resource planning, and operational planning. Individual chapters cover: Simulation Capacity Assessment Network Design Train Routing Robust Timetabling Event Scheduling Track Allocation Blocking Shunting Rolling Stock Crew Scheduling Dispatching Delay Propagation Y1 - 2018 SN - 978-3-319-72152-1 U6 - https://doi.org/10.1007/978-3-319-72153-8 VL - 268 PB - Springer Verlag ER - TY - JOUR A1 - Durmaz, Vedat A1 - Schmidt, Sebastian A1 - Sabri, Peggy A1 - Piechotta, Christian A1 - Weber, Marcus T1 - A hands-off linear interaction energy approach to binding mode and affinity estimation of estrogens JF - Journal of Chemical Information and Modeling Y1 - 2013 VL - 53 IS - 10 SP - 2681 EP - 2688 ER - TY - JOUR A1 - Gelß, Patrick A1 - Klein, Rupert A1 - Matera, Sebastian A1 - Schmidt, Burkhard T1 - Quantum dynamics of coupled excitons and phonons in chain-like systems: tensor train approaches and higher-order propagators JF - The Journal of Chemical Physics Y1 - 2025 U6 - https://doi.org/10.1063/5.0258904 VL - 162 ER - TY - JOUR A1 - Gelß, Patrick A1 - Klein, Rupert A1 - Matera, Sebastian A1 - Schmidt, Burkhard T1 - Solving the time-independent Schrödinger equation for chains of coupled excitons and phonons using tensor trains JF - The Journal of Chemical Physics N2 - We demonstrate how to apply the tensor-train format to solve the time-independent Schrödinger equation for quasi-one-dimensional excitonic chain systems with and without periodic boundary conditions. The coupled excitons and phonons are modeled by Fröhlich–Holstein type Hamiltonians with on-site and nearest-neighbor interactions only. We reduce the memory consumption as well as the computational costs significantly by employing efficient decompositions to construct low-rank tensor-train representations, thus mitigating the curse of dimensionality. In order to compute also higher quantum states, we introduce an approach that directly incorporates the Wielandt deflation technique into the alternating linear scheme for the solution of eigenproblems. Besides systems with coupled excitons and phonons, we also investigate uncoupled problems for which (semi-)analytical results exist. There, we find that in the case of homogeneous systems, the tensor-train ranks of state vectors only marginally depend on the chain length, which results in a linear growth of the storage consumption. However, the central processing unit time increases slightly faster with the chain length than the storage consumption because the alternating linear scheme adopted in our work requires more iterations to achieve convergence for longer chains and a given rank. Finally, we demonstrate that the tensor-train approach to the quantum treatment of coupled excitons and phonons makes it possible to directly tackle the phenomenon of mutual self-trapping. We are able to confirm the main results of the Davydov theory, i.e., the dependence of the wave packet width and the corresponding stabilization energy on the exciton–phonon coupling strength, although only for a certain range of that parameter. In future work, our approach will allow calculations also beyond the validity regime of that theory and/or beyond the restrictions of the Fröhlich–Holstein type Hamiltonians.
