Alexander Polyakov (physicist)

Alexander Markovich Polyakov (born 27 September 1945) is a Russian theoretical physicist. He is known for his important work in understanding very small things, especially in quantum physics and string theory.

Polyakov worked at the Landau Institute in Moscow before moving to the Princeton University in 1989. There, he became the Joseph Henry Professor of Physics Emeritus, a title that shows how much the university values his work.

His research has helped scientists solve many tough problems in physics. Because of his clever ideas and hard work, Polyakov has received many awards and respect from scientists around the world.

Important discoveries

Alexander Polyakov made many important discoveries in physics. He worked on quantum field theory and helped find new ideas like the 't Hooft–Polyakov monopole and the BPST instanton. His work also improved our understanding of string theory and two-dimensional conformal field theory.

Early in his career, Polyakov suggested a way that particles could gain mass. This is called the Higgs mechanism. He shared this idea with other scientists. His work has had a big impact on many areas of theoretical physics.

Honors and awards

Alexander Polyakov received many important awards for his work in physics. He was given the Dirac Medal of the ICTP, the Dannie Heineman Prize for Mathematical Physics in 1986, and later the Lorentz Medal in 1994. He also received the Oskar Klein Medal in 1996, the Harvey Prize in 2010, and the Breakthrough Prize in Fundamental Physics in 2013. In 2020, he was awarded the Max Planck Medal by the German Physical Society.

Polyakov was elected to the Soviet Academy of Sciences in 1984, the French Academy of Sciences in 1998, and the U.S. National Academy of Sciences in 2005.

Political positions

In early 2022, Alexander Polyakov signed two open letters. These letters were written by Russian scientists and Breakthrough Prize winners. They spoke out against Russia's invasion of Ukraine. His actions showed his concern for peace and his support for speaking up against unfair actions.

Famous quotes

Alexander Polyakov shared some interesting thoughts during his career. He once said, “The garbage of the past often becomes the treasure of the present (and vice versa).” He also said, “There are no tables for path integrals.” Another time, he said, “I wanted to learn about small parts of the universe by studying boiling water.”
