To this end, we consider different programs based on the restriction of the evolution to the set of separable (i.e., non-entangled) states, together with the discretization of the space of variables for numerical computations. As a first approach, we apply linear splitting methods to the restricted, continuous equations of motion derived from variational principles. We utilize an exchange interaction Hamiltonian to confirm that the numerical and analytical solutions coincide in the limit of small time steps. The application to different Hamiltonians shows the wide applicability of the method to detect dynamical entanglement. To avoid the derivation of analytical solutions for complex dynamics, we consider variational, numerical integration schemes, introducing a variational discretization for Lagrangians linear in velocities. Here, we examine and compare two approaches: one in which the system is discretized before the restriction is applied, and another in which the restriction precedes the discretization. We find that the \"first-discretize-then-restrict\" method becomes numerically unstable, already for the example of an exchange-interaction Hamiltonian, which can be an important consideration for the numerical analysis of constrained quantum dynamics. Thereby, broadly applicable numerical tools, including their limitations, for studying entanglement over time are established for assessing the entangling power of processes that are used in quantum information theory.</jats:p>"}]},{"citation":{"short":"C.

Starting from the Krotov framework, we reformulate the forward and backward propagation steps using Cayley-type schemes that preserve unitarity and symmetry at the discrete level. This approach eliminates the need for matrix exponentials and commutators, leading to significant computational savings while maintaining higher-order accuracy. We first recall the standard linear setting and then extend the formulation to nonlinear Schrödinger and Gross-Pitaevskii equations using a Cayley-polynomial interpolation strategy. Numerical experiments on state-transfer problems illustrate that the CF-Cayley method achieves the same accuracy as high-order exponential or Cayley-Magnus schemes at substantially lower cost, especially for longtime or highly oscillatory dynamics. In the nonlinear regime, the structure-preserving properties of the method ensure stability and norm conservation, making it a robust tool for large-scale quantum control simulations. The proposed framework thus bridges geometric integration and optimal control, offering an efficient and reliable alternative to existing exponential-based propagators.","lang":"eng"}],"citation":{"ama":"Wembe Moafo BE, Ali U, Meier T, Ober-Blöbaum S.

In this paper we establish an exponential trim turnpike property for a class of optimal control problems with structural properties related to Abelian Lie group symmetries. The key ingredient of our approach is the introduction of an appropriate reduced optimal control problem. We show that extremals of the original problem can be characterized through a reduced Hamiltonian boundary value problem that coincides with the optimality system of the reduced problem. Under a hyperbolicity assumption on the equilibrium of the corresponding reduced Hamiltonian system we prove that optimal trajectories remain exponentially close, up to boundary layers near the endpoints, to a trim primitive defined by the static reduced problem. The theoretical results are illustrated on three representative examples: linear and nonlinear problems with quadratic cost and the Kepler orbital transfer problem.","lang":"eng"}],"date_created":"2026-06-01T09:31:15Z","type":"preprint","department":[{"_id":"94"}],"year":"2026","title":"Non static exponential turnpike property for optimal control problems with symmetries and boundary conditions","status":"public","author":[{"id":"87909","last_name":"Maslovskaya","first_name":"Sofya","full_name":"Maslovskaya, Sofya"},{"id":"16494","full_name":"Ober-Blöbaum, Sina","first_name":"Sina","last_name":"Ober-Blöbaum"},{"id":"95394","full_name":"Wembe Moafo, Boris Edgar","orcid":"0000-0002-6085-8071","last_name":"Wembe Moafo","first_name":"Boris Edgar"}],"date_updated":"2026-06-01T09:35:13Z","publication_status":"submitted","language":[{"iso":"eng"}],"_id":"65744","user_id":"95394"},{"_id":"65747","language":[{"iso":"eng"}],"publisher":"IOP Publishing","doi":"10.1088/1751-8121/ae6d51","user_id":"95394","status":"public","year":"2026","title":"Numerical approaches to entangling dynamics from variational principles","publication_identifier":{"issn":["1751-8113","1751-8121"]},"author":[{"full_name":"Offen, Christian","last_name":"Offen","first_name":"Christian"},{"full_name":"Wembe, Boris","last_name":"Wembe","first_name":"Boris"},{"last_name":"Ares","first_name":"Laura","full_name":"Ares, Laura"},{"last_name":"Sperling","first_name":"Jan","full_name":"Sperling, Jan"},{"first_name":"Sina","last_name":"Ober-Blöbaum","full_name":"Ober-Blöbaum, Sina"}],"date_updated":"2026-06-01T09:43:52Z","publication_status":"published","article_type":"original","date_created":"2026-06-01T09:41:19Z","type":"journal_article","department":[{"_id":"94"}],"publication":"Journal of Physics A: Mathematical and Theoretical","citation":{"ieee":"C.
