Current Research and Scholarly InterestsOur research centers on problems at the interface of quantum and statistical mechanics. Particular themes that occur frequently in our research are hydrogen bonding, the interplay between structure and dynamics, systems with multiple time and length-scales and quantum mechanical effects. The applications of our methods are diverse, ranging from chemistry to biology to geology and materials science. Particular current interests include proton and electron transfer in fuel cells and enzymatic systems, atmospheric isotope separation and the control of catalytic chemical reactivity using electric fields.
Treatment of these problems requires a range of analytic techniques as well as molecular mechanics and ab initio simulations. We are particularly interested in developing and applying methods based on the path integral formulation of quantum mechanics to include quantum fluctuations such as zero-point energy and tunneling in the dynamics of liquids and glasses. This formalism, in which a quantum mechanical particle is mapped onto a classical "ring polymer," provides an accurate and physically insightful way to calculate reaction rates, diffusion coefficients and spectra in systems containing light atoms. Our work has already provided intriguing insights in systems ranging from diffusion controlled reactions in liquids to the quantum liquid-glass transition as well as introducing methods to perform path integral calculations at near classical computational cost, expanding our ability to treat large-scale condensed phase systems. -
Richard McFadden Martin
Adjunct Professor, Applied Physics
BioRichard M. Martin is currently Adjunct Professor in the Department of Applied Physics at Stanford University. He is emeritus Professor of Physics at the University of Illinois Urbana-Champaign, where he served from 1987 to 2008. His undergraduate degree is from the University of Tennessee, Knoxville, and he received his PhD from the University of Chicago in 1969 where his advisor was Morrel H. Cohen. From 1969 to 1971, he was a post-doc at Bell Labs and from 1971 to 1987 was a scientist at the Xerox Palo Alto Research Center. He is author of two books: "Electronic Structure: Basic Theory and Practical Methods (Cambridge University Press, 2004, 2nd edition 2020.) and "Interacting Electrons: Theory and Computational Approaches" along with coauthors Lucia Reining and David Ceperley (Cambridge University Press, 2016). His avocation since 2008 is the African School for Electronic Structure Methods and Applications (ASESMA), where he was a founder and organizer of schools each other year from 2008 to 2025, and chair of the International Advisory Panel.
