Natan Andrei

Distinguished Professor of Physics

Biography

Natan Andrei is a Distinguished Professor in the Department of Physics and Astronomy at Rutgers University. He received his Ph.D. in Physics from Princeton University in 1979 under the supervision of David J. Gross, working on non-perturbative effects in quantum chromodynamics (QCD). His research spans non-perturbative methods, integrability, and strongly correlated quantum systems.

He is widely known for obtaining the exact Bethe-Ansatz solution of the Kondo model, a central problem in the theory of magnetic impurities in metals. His work also includes the solution of the Gross–Neveu model (with J. Lowenstein), as well as foundational contributions to multichannel, nonequilibrium, and correlated-electron impurity physics. His research continues to bridge condensed matter and field theory, emphasizing exactly solvable models and integrable quantum field theories.

Andrei is a Fellow of the American Physical Society and a recipient of the Lars Onsager Prize (2017), awarded “for fundamental contributions to exactly solved models in statistical mechanics and the Kondo/impurity problem.” At Rutgers, he is actively involved in graduate training and mentorship within the Center for Materials Theory.

Research Interests

• Strongly correlated systems in low dimensions
