Giovanni Amelino-Camelia

from Wikipedia, the free encyclopedia

Giovanni Amelino-Camelia (born December 14, 1965 in Naples ) is an Italian theoretical physicist who deals with quantum gravity .

Amelino-Camelia graduated from the University of Naples with a laureate degree in 1990 and received her PhD from Boston University in 1993 . He was then a post-doctoral student at the Massachusetts Institute of Technology until 1995, at the University of Oxford from 1995 to 1997 and at the University of Neuchâtel in 1997/98 and as a Marie Curie Fellow at CERN from 1998 to 2000 . He then went to the La Sapienza University in Rome.

He is considered to be one of the founders of quantum gravity research on astronomical observations. In particular, in 1998 he predicted that light from very distant objects (gamma ray bursts billions of light years away) in the universe should propagate at different speeds depending on the frequency due to the interaction with the quantum structure of space-time. Robert Wagner of the MAGIC telescopes reported in 2005 on the observation of a delayed propagation (up to 4 minutes) of gamma rays of higher energy (shorter wavelength) in a gamma ray burst ( Markarjan 501 ) that occurred 500 million light years away. But there are other explanations and the Fermi Space Telescope was unable to confirm such observations in 2009 (Gamma Ray Burst 7 billion years away).

In 2000 Amelino-Camelia proposed a modification of the special theory of relativity, in which not only the speed of light, but also the Planck length or a corresponding maximum energy is invariant and independent of the observer's inertial system (double special relativity, DSR). The idea behind this is that in a theory of quantum gravity there should also be an invariant smallest length.

He is a fan of loop quantum gravity .

In 2012 he received the Messori Roncaglia Prize of the Accademia dei Lincei and in 2009 the Research Prize of La Sapienza. In 2011 he became a member of the Accademia Pontaniana .

He is on the editorial board of the International Journal of Modern Physics D.
