Life

Luis Álvarez-Gaumé received his PhD in 1981 from the State University of New York at Stony Brook (SUNY), where he had been since 1978, and then was a Junior Fellow at Harvard University from 1981 to 1984 before becoming a professor at Boston University . In 1985 he became a research fellow of the Alfred P. Sloan Foundation ( Sloan Research Fellow ).

He has been a permanent member of CERN's theory department since 1988 .

Álvarez-Gaumé made fundamental contributions to string theory and its mathematical aspects in the 1980s. Together with Edward Witten , he showed in 1983 that, in general, serious anomalies result in quantum field theories with gravitation (whereby anomaly is a technical term that corresponds to certain diagrams that break the gauge symmetries when the theory is quantized ). A little later Michael Green and John Schwarz showed that such anomalies can be avoided in superstring theories with certain symmetry groups. He is also known for applying the techniques developed in theoretical physics ( supersymmetry ) to proofs of the Atiyah-Singer index theorem . He also dealt with other mathematical aspects of string theories such as higher orders of perturbation theory and the associated field theories on Riemann surfaces, quantum groups, as well as the different types of dualities in superstring theories and black holes in string theories, based on the AdS / CFT correspondence to Yang- Mills theories similar to quantum chromodynamics (QCD). In the 1990s he investigated the break of supersymmetry at low energies in exactly solvable model theories (Seiberg-Witten theory of the N = 2 supersymmetric Yang-Mills theory). Most recently (2015) he investigated black hole formation processes in cosmology as well as in accelerator experiments such as at the LHC within the framework of brane theories in n + 4 dimensions with AdS / CFT correspondence.
