On low-rank tensor train approximability for linear nearest neighbor systems
Patrick GelÃ, Sebastian Matera, Reinhold Schneider +1
Low-rank tensor methods are an important tool in the numerical treatment of equations with a high-dimensional state space. Nearest neighbor interaction systems like the Ising model…

Reduced Basis Approach for Convection-Diffusion Equations with Non-Linear Boundary Reaction Conditions
Sebastian Matera, Christian Merdon, Daniel Runge
This paper aims at an efficient strategy to solve drift-diffusion problems with non-linear boundary conditions as they appear, e.g., in heterogeneous catalysis. Since the non-linea…

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…
