Valery Anatolyevich Rubakov (Russian: ? ?, born 16 February 1955 in Moscow, USSR) is a Russian theoretical physicist. His scientific interests include quantum field theory, elementary particle physics, and cosmology. He is affiliated with the Institute for Nuclear Research (INR) of the Russian Academy of Sciences in Moscow.
Rubakov is among the best known of contemporary Russian physical theorists, notable for his studies of the cosmological effects of gauge interactions and for the development of novel ideas of space-time and gravity.
Rubakov first came to prominence for monopole catalysis of proton decay, a remarkable insight on contemporary field theory.'t Hooft and Polyakov had shown that some Grand Unified Theories predict the existence of massive magnetic monopoles. Rubakov pointed out such a monopole would induce proton decay, leaving an observable footprint in the form of electron neutrinos. The phenomenon was independently suggested by Curtis Callan and has become known as the Callan-Rubakov effect.
Together with Mikhael Shaposhnikov, Rubakov was one of the first to model spacetime and gravity using ideas from brane cosmology. Rubakov and Shaposhnikov conjectured that we live on a four-dimensional brane embedded in a higher-dimensional universe. Ordinary particles are confined in a potential well which is narrow along the additional dimensions, thereby localizing matter to the brane.
His paper with Shaposhnikov and Vadim Kuzmin on the effect of electroweak non-conservation of baryon and lepton numbers at high temperatures is considered fundamental to modern theory about the early universe.
In 1999 the Russian Academy of Sciences awarded Rubakov and Kuzmin the Friedmann Prize "for a series of works on the formation of the baryon asymmetry of the universe". He received the 2003 ITEP Pomeranchuk Prize "for pioneering contribution [sic] to developing and novel application of nonperturbative methods in field theory". In 2005 he was awarded the INR Markov Prize for fundamental physics with Mikhael Shaposhnikov. In 2008 he won the J. Hans D. Jensen Prize of the University of Heidelberg, and the Bruno Pontecorvo Prize "for his essential contributions to the study of close interrelation among particle physics, astrophysics and cosmology, and to the elaboration of a fundamentally new theory of physical space". In 2010 he received the Karlsruhe Institute of Technology Julius Wess Prize. The award was presented as part of a celebration of 50 years of teaching and research in particle physics at Karlsruhe, at which Rubakov gave a lecture entitled "Towards understanding the origin of inhomogeneities in the Universe" . In 2016 Rubakov was awarded the Demidov Prize "for fundamental theoretical contributions to the foundations of physics: quantum field theory, elementary particle physics, gravity, the theory of the early universe".
