Erik Deumens

Director / UF Information TechnologyResearch Computing and scientist in the Department of Chemistry and Department of Physics.

  • With Beverly Sanders, Hai-Ping Cheng, Jim Freericks, and Chenlog Li, I am preparing an proposal for an NSF Quantum Leap Challenge Institute, due Sept. 2020.
  • On September 30, 2019, I give the Mathematics Colloquium with the title “On using a functional measure to capture the probabilistic character of measurement in quantum mechanics
  • On April 4, 2019, I gave the Physics Colloquium with the title “Quantum mechanics: How Einstein and Bohr led everybody astray.
  • These talks give an introduction and summary of the paper “On Classical Systems and Measurements in Quantum Mechanics”, Erik Deumens, Quantum Studies: Mathematics and Foundation, (2019) 6(4), 481-517 (37 pages) doi: 10.1007/s40509-019-00189-3 (published online(PDF) .

Areas of Interest/Research

  • On Mar 14, 2019, my paper on the foundations and interpretation of quantum mechanics was accepted for publication. It is extracted from the book on quantum mechanics that I submitted to the publisher on Apr 18, 2017 at the recommendation of the reviewers. I have been working on the book since 2004 and on the interpretation of quantum mechanics since 1975, when I first learned about quantum mechanics. Check my Research page for details.
  • Since 2015, this includes building a secure infrastructure for research with restricted data that is demonstrably complaint with NIST 800-53 and 800-171 controls.
  • From 2010, I am an administrator, running the department of Research Computing in UF Information Technology, which provides infrastructure for researchers at UF and their collaborators to perform the computational and data management tasks that are part of modern research in all fields of scholarship, engineering, science, and mathematics.
  • I have always been very interested in quantum mechanics and the theories of special and general relativity. Most of my scientific career, I have worked in computational molecular physics.


I have been a computational physicist and chemist during most of his career. I am the principal author of the time dependent approach to molecular dynamics that treats both the atomic nuclei and the electrons explicitly, called electron nuclear dynamics. I am the author of the ENDyne software that implements this method. I also created of the super instruction architecture, an approach to support rapid programming of complex algorithms that need to scale to tens of thousands of compute cores. ACES III was written using this architecture. Now the successor ACES 4 has been created to further optimize the features of this approach. I have provided support and consulting services for compuational scientists in numerous ways, at UF and an various places around the US.
