Sutherland, Calogero and Gaudin win 2019 Dannie Heineman Prize for Mathematical Physics
WASHINGTON, D.C., OCTOBER 23, 2018 — The American Institute of Physics (AIP) and the American Physical Society (APS) announced today that Bill Sutherland of the University of Utah, Francesco Calogero of the Sapienza University of Rome and Michel Gaudin of the Commissariat à l'énergie atomique (CEA) Saclay are the winners of the 2019 Dannie Heineman Prize for Mathematical Physics.
Awarded annually by AIP and APS on behalf of the Heineman Foundation, the prize honors significant contributions to the field. Sutherland, Calogero and Gaudin were cited "for profound contributions to the field of exactly solvable models in statistical mechanics and many body physics, in particular the construction of the widely studied Gaudin magnet and the Calogero-Sutherland, Shastry-Sutherland and Calogero-Moser models."
They will share the prize's $10,000 award and will be honored in a special ceremonial session next year at the APS March Meeting in Boston.
"On behalf of AIP and the Heineman Foundation, I am pleased to congratulate Drs. Sutherland, Calogero and Gaudin for their key contributions to mathematical physics," said AIP CEO Michael Moloney. "Each of these three arrived at this pinnacle in their careers following separate paths, along the way making numerous invaluable contributions to science and humanity."
"On behalf of APS, I congratulate the winners of the 2019 Dannie Heineman Prize. I am delighted that the outstanding research contributions of Sutherland, Calogero, and Gaudin have been recognized in this way," said APS CEO Kate Kirby.
The breakthrough accomplishments by Calogero, Sutherland and Gaudin are still influential today among physicists as well as applied and pure mathematicians worldwide.
BACKGROUNDER: Adding to the House that Hans Bethe Built
Michel Gaudin began his studies working on random matrices. He built on the work of Hans Bethe by refining the elder scientist's equations that predicted collective behaviors in electrons while trying to solve some of the earliest problems of quantum mechanics. This approach enabled him to obtain the solution of the Schrödinger equation for a system of spin one-half fermions with a delta (attractive) potential. Based on his thesis work, he later developed a magnet model (the Gaudin magnet) that opened the door to thermodynamics.
"It is not specifically one-dimensional," Gaudin said. "It has a large number of parameters that allows for the description of interactions of a photon mode with a mix of atoms represented by two-level systems."
In 1971, Calogero developed the first nontrivial many-body problem with two-body forces that could be exactly solved. Sutherland independently obtained the identification and solution of a variant of this model in a statistical mechanics context.
"I am interested in statistical mechanics, quantum mechanics and the connections between the two," Sutherland said. "In this way, I have proceeded throughout my career."
During his graduate studies with professor C.N. Yang, Sutherland developed an exact solution of a model of two-dimensional ferroelectrics in an arbitrary external electric field. Working one summer with the brothers C.N. Yang and C.P. Yang, Sutherland extended these solutions, showing the connection with the one-dimensional quantum Heisenberg-Ising model. Soon after, he came across Calogero's work using an exact wave function of a one-dimensional quantum system. While Calogero's solution was an unbound scattering state, Sutherland figured out how to put the model "in a box" and calculate the thermodynamics for the Calogero-Sutherland model that has been applied in many branches of physics, including quantum fractional Hall effect, generalized exclusion statistics and even black hole physics.
Later the theoretical Shastry-Sutherland model was introduced and became important with the discovery of magnetization plateaus obtained with SrCu2 (BO3)2 under high magnetic ?elds. This technique enabled various experimental studies, including magnetization, specific heat, inelastic neutron scattering, far-infrared studies of electron spin resonance, Raman scattering and nuclear magnetic resonance.
Finally, the Calogero-Moser model is a one-dimensional many-body problem that can be explicitly solved. The model touches many fields of mathematics, including algebraic geometry, representation theory, deformation theory, homological algebra and Poisson geometry. It now plays a role in research areas from theoretical physics, including soliton theory, quantum field theory, string theory, solvable models of statistical mechanics, condensed matter physics and quantum chaos, to pure mathematics, including representation theory, harmonic analysis, theory of special functions, dynamical systems, random matrix theory and complex geometry.
"I feel, at my old age, greatly honored by this recognition," Calogero said. "Particularly so given the list of previous awardees."
