We bid farewell to Verena, who leaves to begin a postdoc position at Caltech. Good luck, Verena!
Amazing group news! Congratulations to Norah, who will be an Assistant Professor of Chemistry at NYU (starting January 2024), and congratulations to Hong-Zhou, who will be an Assistant Professor of Chemistry and Biochemistry at the University of Maryland (starting summer 2024)!
Verena's tour de force Highly accurate electronic structure of metallic solids from coupled-cluster theory with nonperturbative triple excitations is posted to the arXiv. A significant improvement over CCSD (see our previous paper), CCSDT recovers 92-99% of the exact correlation energy of the uniform electron gas at metallic densities and gets within a few millihartrees of the experimental cohesive energy of lithium.

We work on a variety of quantum-mechanical problems motivated by excited-state phenomena. This research occurs at the fascinating interface of physical chemistry, condensed-matter physics, and materials science.
Building on modern theories of quantum dynamics, we develop powerful simulation techniques for nonequilibrium and time-resolved spectroscopies. These new tools enable the accurate simulation of extremely large and complex sytems, providing new insights into excited-state structure and dynamics.
We are actively exploring the excited-state behavior of fundamentally interesting and technologically promising materials, especially those that are anisotropic, layered, or low-dimensional. Particular materials of interest include conjugated polymers, organic molecular crystals, and quasi-two-dimensional inorganic semiconductors.
Aiming towards highly accurate but insightful descriptions of electronic excitations, we formulate and apply electronic structure methods adapted for the condensed phase. Some of our favorite tools are low-energy effective theories, many-body diagrammatics, and coupled-cluster techniques.
Timothy Berkelbach is an Associate Professor in the Department of Chemistry at Columbia University. He received his B.A. in physics and chemistry from NYU in 2009 and his Ph.D. in chemical physics from Columbia in 2014. From 2014 to 2016, he was a postdoctoral fellow in the Princeton Center for Theoretical Science, and from 2016 to 2018, he was a Neubauer Family Assistant Professor in the Department of Chemistry and the James Franck Institute at the University of Chicago. He moved to Columbia in 2019 and received tenure in 2022. From 2019 to 2022, he was also a Research Scientist in the Center for Computational Quantum Physics at the Flatiron Institute, where he is now a Visiting Scholar.
