Alexander "Sasha" Abramovich Belavin is a Russian physicist, known for his contributions to string theory
.
He is a professor
at the Independent University of Moscow and is researcher at the Landau Institute of Theoretical Physics.
Also, he is a member of the editorial board of the Moscow Mathematical Journal
.
He forestood the discovery of BPST instanton
(1975) which aided the understanding of the chiral anomaly
and gave new directions within quantum field theory
.
With G. Avdeeva he showed evidence of new coupling regimes for gauge field theory (1973).
The Belavin S-matrices were exactly solvable models in two-dimensional relativistic theories in (1981).
He co-authored the BPZ paper (1984) with Alexander Polyakov and Alexander Zamolodchikov
on 2D conformal field theories, which became important for string theory.
With Vadim Knizhnik he made the Belavin-Knizhnik's theorem on dual amplitudes in string theory (1986).
String theory
String theory is an active research framework in particle physics that attempts to reconcile quantum mechanics and general relativity. It is a contender for a theory of everything , a manner of describing the known fundamental forces and matter in a mathematically complete system...

Professor
A professor is a scholarly teacher; the precise meaning of the term varies by country. Literally, professor derives from Latin as a "person who professes" being usually an expert in arts or sciences; a teacher of high rank...

He forestood the discovery of BPST instanton
BPST instanton
The BPST instanton is the instanton with winding number 1 found by Alexander Belavin, Alexander Polyakov, Albert Schwarz and Yu. S. Tyupkin. It is a classical solution to the equations of motion of SU Yang-Mills theory in Euclidean space-time , meaning it describes a transition between two...
(1975) which aided the understanding of the chiral anomaly
Chiral anomaly
A chiral anomaly is the anomalous nonconservation of a chiral current. In some theories of fermions with chiral symmetry, the quantization may lead to the breaking of this chiral symmetry. In that case, the charge associated with the chiral symmetry is not conserved.The non-conservation happens...
and gave new directions within quantum field theory
Quantum field theory
Quantum field theory provides a theoretical framework for constructing quantum mechanical models of systems classically parametrized by an infinite number of dynamical degrees of freedom, that is, fields and many-body systems. It is the natural and quantitative language of particle physics and...
