Welcome to the website of Gershom (Jan M.L.) Martin and his research group at Weizmann.
Our primary field of research is computational quantum chemistry. Our research philosophy is based on a “two-dimensional synergy”:
in one dimension, between theory and applications
in the other dimension, between wavefunction-based ab initio methods and DFT (density functional theory).
DFT applications mostly focus on homogenous catalysis by late transition metal complexes (collaborations with the experimental groups of David Milstein, Ronny Neumann, and Milko van der Boom). Some of these applications are related to renewable energy and hydrogen storage.
Ab initio applications mostly focus on benchmarking DFT methods, but also on atmospheric chemistry and combustion processes. Recently we have ventured increasingly into noncovalent interactions, especially between biomolecules.
Very accurate computational thermochemistry is the centerpiece of our ab initio theory work, most recently with our development of “W4 theory” (Weizmann-4), which offers unprecedented accuracy at still-tractable computational cost. Increasingly, we have come to rely on explicitly correlated methods because of their superlative basis set convergence properties.
Our DFT development has been centered mostly on developing more ‘universal’ functionals. Our BMK functional (Boese-Martin for Kinetics) was the first to yield similar accuracy for equilibrium thermochemistry and barrier heights, while our recent DSD-PBEP86-D3BJ and DSD-PBEP86-NL double hybrids offers accuracy and universality not dissimilar to composite ab initio methods — but at a fraction of the cost.
