Robert Sims

Robert Sims is a Professor in the Department of Mathematics at the University of Arizona, where he has been a faculty member since 2008, progressing from Assistant to Associate and then full Professor. His primary academic affiliation is with the Department of Mathematics, and he is actively involved in research and teaching within the mathematical physics community.

• Education: Ph.D. in Applied Mathematics, University of Alabama at Birmingham (2001), advised by Gunter Stolz.
• Academic Positions: Professor (2021–present), Associate Professor (2013–2021), Assistant Professor (2008–2013), with prior postdoctoral roles at the University of Vienna, UC Davis, Princeton University, and UC Irvine.

Robert Sims's research is centered on mathematical physics and analysis, with deep contributions to the understanding of quantum spin systems, disordered media, and quantum dynamics. His work particularly emphasizes Lieb-Robinson bounds, which quantify the speed of information propagation in quantum lattice systems, and their applications to entanglement, spectral theory, and many-body localization. He has made significant advances in the stability of spectral gaps, automorphic equivalence in gapped phases, and localization phenomena in disordered oscillator and spin systems. His research often involves rigorous analytical methods applied to problems in statistical mechanics and quantum theory.

The recent publications of Robert Sims, spanning from 2019 to 2024, reveal a sustained focus on the structure and dynamics of quantum lattice systems. Key themes include quasi-locality, Lieb-Robinson bounds for fermionic and long-range systems, stability of topological order, and entanglement in disordered models. His work frequently involves collaborations with leading figures such as Bruno Nachtergaele and Gunter Stolz, and is published in prestigious journals like Communications in Mathematical Physics and Annales Henri Poincaré.
