Lars Onsager Prize

Lars Onsager Prize is a prestigious award presented by the American Physical Society to recognize outstanding research in theoretical statistical physics. Named in honor of the Nobel laureate Lars Onsager, the prize celebrates contributions that embody the profound depth and mathematical rigor characteristic of his work. It is considered one of the highest honors in the field of statistical mechanics and related areas of theoretical physics.

History and establishment

The prize was established in 1995 through an endowment from his family and colleagues, commemorating the legacy of Lars Onsager, who received the Nobel Prize in Chemistry in 1968 for his reciprocal relations in irreversible thermodynamics. The creation of the award was championed by prominent figures within the American Physical Society's Division of Condensed Matter Physics, which oversees its administration. Its establishment filled a significant niche, providing dedicated recognition for advances in statistical physics, a field profoundly shaped by Onsager's exact solution of the two-dimensional Ising model.

Selection criteria and laureates

The prize is awarded annually for outstanding research in theoretical statistical physics, including the broad range of principles governing condensed matter physics, biological physics, and quantum fluids. The selection committee, appointed by the American Physical Society, evaluates nominees based on the impact, originality, and depth of their contributions to the field. Laureates receive a monetary award, a certificate, and are invited to deliver a prize lecture at the annual March Meeting of the American Physical Society.

Notable recipients and contributions

Recipients include many leading theorists who have shaped modern physics. Early laureates like Leo P. Kadanoff were honored for foundational work on scaling laws and the renormalization group, concepts central to understanding phase transitions. Subsequent winners such as J. Michael Kosterlitz and David J. Thouless were recognized for their work on topological phase transitions, prior to their receipt of the Nobel Prize in Physics. More recent honorees like Andrea J. Liu and Sidney R. Nagel have been cited for pioneering studies in jamming and the physics of disordered systems.

Other distinguished laureates include Giorgio Parisi for his work on spin glasses and complex systems, Anton Zee for contributions to quantum field theory and condensed matter physics, and Boris Shraiman for insights into pattern formation and turbulence. The work of Piers Coleman on heavy fermion systems and Kondo effect, and of Xiao-Gang Wen on topological order and quantum entanglement, further illustrates the prize's scope in honoring transformative theoretical advances.

Significance and impact

The award holds considerable significance within the global physics community, serving as a benchmark for excellence in theoretical statistical physics. It highlights the continuing vitality of fields initiated by Lars Onsager, John von Neumann, and Paul Ehrenfest. By recognizing work that often bridges mathematics, computer science, and biology, the prize underscores the interdisciplinary nature of modern statistical physics. Its laureates frequently see their prize-winning research influence adjacent fields like materials science, neuroscience, and quantum information theory.

Administration and presentation

The prize is administered by the American Physical Society, specifically through its Topical Group on Statistical and Nonlinear Physics within the Division of Condensed Matter Physics. The selection process involves a dedicated committee that solicits nominations from the international community. The award is formally presented during a ceremonial session at the annual March Meeting, where the laureate delivers a special lecture. The award's endowment is managed to ensure its longevity, supporting the recognition of groundbreaking work for future generations of physicists.
