Albert J. Libchaber

Wolf Prize Laureate in Physics 1986

The Physics Prize Committee for 1986 has unanimously decided to recommend that the Wolf Prize in Physics be shared jointly by Mitchell J. Feigenbaum and Albert J. Libchaber.

Albert J. Libchaber
University of Chicago
Chicago, Illinois, USA

“for his brilliant experimental demonstration of the transition to turbulence and chaos in dynamical systems.”

Mitchell J. Feigenbaum and Albert J. Libchaber together have opened up an entirely new field of research.

Professor Albert J. Libchaber is one of the leading figures in experimental condensed matter physics. He has made the first experimental observation of the bifurcation cascade that leads to chaos and turbulence in convective Rayleigh-Benard systems. Considering the complexity of all past work on turbulence, Libchaber’s experiments are astounding in their simplicity and elegance. Using microbolometers (scale 1ч) engraved in the convective cell he was able to observe temperature fluctuations without perturbing the environment. In that way, he clearly observed the bifurcations that lead to chaos: period doubling, possibly accompanied by locking of several incommensurate frequencies. The theoretical predictions of Feigenbaum are thus entirely confirmed. His first work was done on 4He;  he has been using mercury, in which an applied magnetic field provides an additional degree of freedom. The experiment is so perfect that it can measure quantitatively the Feigenbaum critical exponents that characterize the cascade to chaos.

Chien-Shiung Wu
Columbia University
New York, N.Y., USA

“for her persistent and successful exploration of the weak interaction which helped establish the precise form and the non conservation of parity for this new natural force.”

Professor Chien-Shiung Wu has done outstanding experimental work on the mechanism of beta disintegration, and thereby, of weak interactions generally. This work extended mostly from 1948 to 1963. In addition, she has made important contributions to several other fields of fundamental physics, to physics Instrumentation, and recently, to biology.

In her most famous work, she demonstrated that the direction of emission of beta rays is strongly correlated with the direction of the spin of the emitting nucleus. This showed that parity is not conserved in beta disintegration, in accord with the epochal theory of Lee and Yang, which had been developed just a few months before.

The success of this theory raised the problem of the exact coupling between the nucleon, which undergoes beta decay, and the electron and neutrino, which are emitted in this decay.

Among Wu’s other contributions we want to mention her demonstration that the two quanta from the annihilation of positrons and electrons are polarized at right angles to each other, as they should be according to Dirac’s theory. This proves that electron and positron have opposite parity. In recent years (1966 to 1971), Wu has made a thorough study of the X ray spectra of muonic atoms and has become interested in biological problems, especially the structure of hemoglobin. Her Moessbauer studies of this substance have given surprising results, and have considerably clarified its structure.

Chien-Shiung Wu

“for her persistent and successful exploration of the weak interaction which helped establish the precise form and the non conservation of parity for this new natural force.”

Professor Chien-Shiung Wu has done outstanding experimental work on the mechanism of beta disintegration, and thereby, of weak interactions generally. This work extended mostly from 1948 to 1963. In addition, she has made important contributions to several other fields of fundamental physics, to physics Instrumentation, and recently, to biology.

In her most famous work, she demonstrated that the direction of emission of beta rays is strongly correlated with the direction of the spin of the emitting nucleus. This showed that parity is not conserved in beta disintegration, in accord with the epochal theory of Lee and Yang, which had been developed just a few months before.

The success of this theory raised the problem of the exact coupling between the nucleon, which undergoes beta decay, and the electron and neutrino, which are emitted in this decay.

“for her persistent and successful exploration of the weak interaction which helped establish the precise form and the non conservation of parity for this new natural force.”

Professor Chien-Shiung Wu has done outstanding experimental work on the mechanism of beta disintegration, and thereby, of weak interactions generally. This work extended mostly from 1948 to 1963. In addition, she has made important contributions to several other fields of fundamental physics, to physics Instrumentation, and recently, to biology.

In her most famous work, she demonstrated that the direction of emission of beta rays is strongly correlated with the direction of the spin of the emitting nucleus. This showed that parity is not conserved in beta disintegration, in accord with the epochal theory of Lee and Yang, which had been developed just a few months before.

The success of this theory raised the problem of the exact coupling between the nucleon, which undergoes beta decay, and the electron and neutrino, which are emitted in this decay.

Among Wu’s other contributions we want to mention her demonstration that the two quanta from the annihilation of positrons and electrons are polarized at right angles to each other, as they should be according to Dirac’s theory. This proves that electron and positron have opposite parity. In recent years (1966 to 1971), Wu has made a thorough study of the X ray spectra of muonic atoms and has become interested in biological problems, especially the structure of hemoglobin. Her Moessbauer studies of this substance have given surprising results, and have considerably clarified its structure.

Among Wu’s other contributions we want to mention her demonstration that the two quanta from the annihilation of positrons and electrons are polarized at right angles to each other, as they should be according to Dirac’s theory. This proves that electron and positron have opposite parity. In recent years (1966 to 1971), Wu has made a thorough study of the X ray spectra of muonic atoms and has become interested in biological problems, especially the structure of hemoglobin. Her Moessbauer studies of this substance have given surprising results, and have considerably clarified its structure.

Chien-Shiung Wu

“for her persistent and successful exploration of the weak interaction which helped establish the precise form and the non conservation of parity for this new natural force.”

Professor Chien-Shiung Wu has done outstanding experimental work on the mechanism of beta disintegration, and thereby, of weak interactions generally. This work extended mostly from 1948 to 1963. In addition, she has made important contributions to several other fields of fundamental physics, to physics Instrumentation, and recently, to biology.

In her most famous work, she demonstrated that the direction of emission of beta rays is strongly correlated with the direction of the spin of the emitting nucleus. This showed that parity is not conserved in beta disintegration, in accord with the epochal theory of Lee and Yang, which had been developed just a few months before.

The success of this theory raised the problem of the exact coupling between the nucleon, which undergoes beta decay, and the electron and neutrino, which are emitted in this decay.
