Nikolaos Emmanuel Mavromatos (Νικόλαος Εμμανουήλ Μαυρομάτος; born 15 November 1961 in Athens) is a Greek theoretical physicist, specialising in string theory, particle physics, and cosmology.
In 1979 Mavromatos entered the School of Physical Sciences of the National and Kapodistrian University of Athens (abbr.
[1] During his undergraduate study, Mavromatos learned quantum theory from Fokion T. Hadjioannou and developed collaborative friendships with G. A. Diamandas and B. C.
His doctoral dissertation Aspects of the low energy limit of string theories was supervised by Christopher Llewellyn Smith and M.
He mathematically demonstrated that such hypothetical violations of conformal symmetries might be linked to spacetime defects involving theories of quantum gravity.
[4] The 1998 paper Tests of quantum gravity from observations of γ-ray bursts by Giovanni Amelino-Camelia, John Ellis, Nikolaos Mavromatos, Dimitri Nanopoulos, and Subir Sarkar [5] has more 1700 citations.
With John Ellis, Dimitri Nanopoulos, and other collaborators, Mavromatos suggested possible tests of the constancy of the velocity of light[6] and possible optical properties of the vacuum related to D-branes.
