Francesco Iachello

from Wikipedia, the free encyclopedia

Francesco Iachello (born January 11, 1942 in Francofonte ) is an Italian theoretical physicist who mainly works on nuclear and molecular physics . Together with Akito Arima, he is the creator of the " Interacting Boson Model ".

Life

Iachello received his doctorate in nuclear engineering in 1964 at the Turin Polytechnic and in physics in 1969 at MIT . He has been at Yale University since 1978 , where he is currently JWGibbs Professor of Physics and Chemistry.

Iachello received the Chiaudano Prize in 1964 and was a Fulbright Fellow in 1968 . In 1990 he received the Wigner Medal , in 1991 the Taormina Prize and the Dutch AKZO Prize . In 1993 he and Akito Arima received the Tom W. Bonner Prize for Nuclear Physics from the American Physical Society , of which he became a fellow in 1979. He is a member of the Dutch and Croatian Academy of Sciences . In 1997 he received the Prize of the Century from the Italian Physical Society . In 2002 he received the Lise Meitner Prize of the European Physical Society . He is an honorary doctor from the Universities of Ferrara , Seville , Darmstadt and the Chung Yuan University in China. He has been an external member of the Academia Europaea since 2013 .

Iachello is known for his application of algebraic methods (Lie algebras) to the study of the spectra of atomic nuclei and molecules. In 1974 he and Akito Arima introduced the “ Interacting Boson Model ” into nuclear physics, in which collective stimuli are described with the help of the unitary group U (6). This is based on the idea of ​​a description by pairs of neutrons and protons instead of the nucleons themselves. The pairs are treated as bosons with different angular momenta (s and d bosons, corresponding to angular momenta 0 and 2). The interaction with unpaired fermions (odd nuclei) is described in an extension of the model with supersymmetric algebras.

In recent times he has mainly been concerned with the investigation of the quantum mechanical dynamics of molecules (e.g. quantum phase transitions , polymer dynamics ) using algebraic methods, which Iachello started with as early as 1981 ( Vibron Model ).
