Reframing the coupling force of adaptive resolution simulation in terms of the Liouville-type hierarchy for open systems
Julian F. Hille, Rupert Klein
In this work, we present a novel perspective on the coupling force employed to compensate the interface artifacts prevalent in adaptive resolution simulations (AdResS) of open many…

Quantum dynamics of coupled excitons and phonons in chain-like systems: tensor train approaches and higher-order propagators
Patrick GelÃ, Sebastian Matera, Rupert Klein +1
We investigate tensor-train approaches to the solution of the time-dependent Schrödinger equation for chain-like quantum systems with on-site and nearest-neighbor interactions onl…
