Abstract

We present a new general framework for solving the monodimensional Smoluchowski equation using a discrete variable representation (DVR) based on the so called sinc basis set. The reliability of our implementation is assessed by comparing the convergence of diffusive operator eigenvalues calculated using our method and using a simple finite difference scheme for some model diffusive problems. The results here presented open encouraging possibilities for dealing with more complicated systems, where additional coordinate dependent terms in the equation or multidimensional treatments are needed and traditional methods often become unfeasible.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
