Giorgio Benedek

Giorgio Benedek (born 4 February 1941) is an Italian physicist, academic and researcher. He is an emeritus Professor of Physics of Matter at University of Milano-Bicocca and Director of the International School of Solid State Physics at Ettore Majorana Foundation and Centre for Scientific Culture.

Benedek's original theoretical interest in the dynamics and vibrational response functions of defects in solids has been extended to various research areas regarding low-dimensional systems, like surface dynamics and surface phonon spectroscopy, the topology and physics of cluster-assembled carbon, and the physics of He quantum droplets and solids.

Benedek is emeritus foreign member of the Royal Academy of Belgium, member of the Istituto Lombardo – Accademia di Scienze e Lettere, of the Istituto di Studi Superiori Gerolamo Cardano, a fellow of the European Academy of Sciences, of the European Physical Society, and of the Italian Physical Society.

Career Benedek studied at the University of Milano and received his Doctoral degree in physics, and his University Teaching Qualification in Solid State Physics in 1965 and 1970, respectively. Benedek worked at the Joint Research Centre (JRC) in Ispra before being appointed for a permanent research position at Consiglio Nazionale delle Ricerche (CNR) from 1967 till 1984. This appointment allowed him to teach at the University of Milano as a lecturer of Physics for Biological Sciences from 1970 till 1984. In the following year, he was promoted to associate professor, then in 1986 Full Professor of Structure of Matter. In this position he moved in 1998 to the Department of Materials Science of the University of Milano-Bicocca. Benedek was appointed as an emeritus Professor of Physics of Matter at this university after his retirement in 2011.

Benedek has been a regular visiting scientist at the Max-Planck Institut (MPI) für Festkörperforschung, Stuttgart (1978–1987), the MPI für Strömungsforschung (now Dynamik und Selbstorganisation) in Göttingen, Germany, since 1980, and at Donostia International Physics Center (DIPC) since 2003. He directs the International School of Solid State Physics since 1990, and is a co-director of the International School of Complexity at the Ettore Majorana Foundation and Centre for Scientific Culture

The collaboration of Benedek with Jan Peter Toennies led to a full development of HAS surface phonon spectroscopy for different classes of materials. Within this collaboration, Benedek and coworkers predicted or explained several inelastic HAS effects like the kinematical focusing, the anomalous longitudinal resonance, the inelastic bound-state resonance-enhancement and the quantum sonar effect, by which HAS from a conducting surface can detect deep subsurface phonons via the electron-phonon interaction.

Benedek with Chakram S. Jayanthi, Winfried Kress and Heinz Bilz developed the multipole-expansion model (also termed pseudo-charge model) for the analysis of surface dynamics and inelastic HAS spectra. In the same group at the MPI-FKF in Stuttgart, Benedek joined Bilz and Annette Bussmann-Holder in a series of papers presenting a new nonlinear electron-phonon theory of ferroelectricity. Karl-Alex Müller and Benedek started in 1989 a periodic series of Erice workshops on high-temperature superconductivity.
