Erik Deumens

Director of UF Information Technology Research Computing and scientist in the Department of Chemistry and Department of Physics.

  • Artificial Intelligence A lot of effort is now going into the UF AI initiative.
  • Quantum Computing With Beverly Sanders, Hai-Ping Cheng, Jim Freericks, Meera Sitharam, and Chenglong Li, I have submitted a proposal for an NSF Quantum Leap Challenge Institute in Sept. 2020. In preparation for that proposal, Beverly and I taught a class on quantum information science during the spring semester that was a lot of fun. All of us, students, guest lecturers, and teachers learned a lot. As a final exam, the students had to finish a project in groups of up to 3 people on a topic of their choice. This resulted in a great set of projects and reports!
  • Foundations of Quantum Mechanics
    • 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

  • Now I am finalizing a mathematical paper on the construction of quantum fields. I have been working on this problem since 1980, first at a low rate, then more intensely since 2004, and most intensely since 2017.
  • 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, my duties includes building a secure infrastructure for research with restricted data that is demonstrably complaint with NIST 800-53 and 800-171 controls. In 2020, that includes implementing the new Cybersecurity Maturity Model Certification (CMMC). I am also working on HITRUST certification for HiPerGator.
  • 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.
