Zoltán G. Soos

Zoltán G. Soos is a Professor of Chemistry at Princeton University, where he has been since 1966. His research bridges chemistry and physics, focusing on organic molecular solids, ion radicals, charge transfer salts, neutral-ionic phase transitions, and one-dimensional spin systems. He collaborates globally, including with Sandia National Laboratories, the University of Parma, and the Indian Institute of Science. Soos earned a B.A. in Chemistry and Physics from Harvard University and a Ph.D. from the California Institute of Technology, followed by a National Science Foundation postdoctoral fellowship at Stanford.

His research interests span materials science and theoretical chemistry, with emphasis on electronic excitations in conjugated polymers, triplet spin excitons, quantum spin liquids, and frustrated magnetic systems. He has pioneered studies on bond-order wave phases in Hubbard models and explored phase transitions driven by Peierls mechanisms. His work has practical implications for electronic device development.

Publications highlight contributions to understanding spin-flop transitions, antiferromagnetic phases in ladder compounds, and collective charge transfer in organic thin films. Collaborations with experimental groups have advanced x-ray scattering analysis of phase transitions and neutron diffraction studies of magnetic materials.

Soos has advised numerous students and maintains active research partnerships across institutions. His work integrates computational modeling with experimental data, particularly in analyzing quantum phenomena in low-dimensional systems.
