The field of quantum field theory, often associated with the study of elementary particles, has earned recognition for its applications in various domains outside of particle physics. The 2024 Breakthrough Prize in Fundamental Physics has been awarded to John Cardy and Alexander Zamolodchikov for their groundbreaking work in repurposing quantum field theory for condensed-matter, statistical physics, and gravitational studies.

Quantum field theory involves complex mathematical equations that describe the behavior of elementary particles. However, both Cardy, a professor emeritus from the University of Oxford, and Zamolodchikov, from Stony Brook University in New York, have demonstrated the versatility of quantum field theory in other fields of physics.

Cardy’s contributions have focused on applying quantum field theory to phase transitions, percolation theory, and quantum spin chains. His pioneering work showed that computations on small systems could provide insights into the behavior of infinitely large systems. By using the mathematical insights of two-dimensional conformal field theory (2D CFT), Cardy was able to calculate critical exponents that describe phase transitions.

Zamolodchikov, on the other hand, explored the application of quantum field theory in critical phenomena and fluid turbulence. His realization that solving problems in 2D CFT could serve as a starting point for studying generic quantum fields opened up new avenues for research.

The impact of their work extends beyond their respective fields. Researchers in condensed-matter physics have benefited from their contributions to 2D surfaces, while string theorists have found value in modeling the motion of 1D strings using Zamolodchikov and Cardy’s insights.

The Breakthrough Prize recognizes the profound contributions of Cardy and Zamolodchikov to statistical physics and quantum field theory, which have far-reaching applications in various branches of physics and mathematics. Their achievements highlight the power of 2D physics, where simplicity and elegance coexist with mathematical richness and complexity.
