Towards an efficient multiscale modeling of low-dimensional reactive systems: study of numerical closure procedures
Giacomo Mazzi, Yannick De Decker, Giovanni Samaey
In this paper, we present a study on how to develop an efficient multiscale simulation strategy for the dynamics of chemically active systems on low-dimensional supports. Such reac…

Dimensional Reductions for the Computation of Time-Dependent Quantum Expectations
Giacomo Mazzi, Ben Leimkuhler
We consider dimensional reduction techniques for the Liouville-von Neumann equation for the evaluation of the expectation values in a mixed quantum system. In applications such as…

Expectations from the Liouville-von Neumann Equation Using Chebyshev Expansion
Giacomo Mazzi, Ben Leimkuhler
We consider a natural dimension reduction technique for the Liouville-von Neumann equation for a mixed quantum system based on evaluation of a trace formula combined with a direct…
