Vladimir Borisovich Braginsky

from Wikipedia, the free encyclopedia

Wladimir Borissowitsch Braginski ( Russian Владимир Борисович Брагинский ; born August 3, 1931 in Moscow ; † March 29, 2016 ibid) was a Russian physicist and university professor .

Life

Braginski studied at the physics faculty of Lomonossow University Moscow (MGU) with a degree in 1954. In 1955 he became a research assistant at the chair for vibration physics . He defended his candidate dissertation in 1959 and his doctoral dissertation in 1967 . In 1969 he was appointed professor. In the 1970s he headed the Department of Radiophysics and Electronics in the Faculty of Physics. 1987–2001 he headed the chair for molecular physics and physical measurements and 2001–2002 the chair for vibrational physics . In 1990 he was elected Corresponding Member of the Academy of Sciences of the USSR (AN-SSSR, since 1991 Russian Academy of Sciences (RAN)). In 1995 he became a member of the Academia Europaea . He gave guest lectures at the Niels Bohr Institute (1996) and at Uppsala University (1999). In 2004 he became an external honorary member of the American Academy of Arts and Sciences and in 2006 an external member of the National Academy of Sciences .

Braginski was an internationally highly respected experimental physicist and theorist . In 1967 he predicted and demonstrated ponderomotive friction and rigidity effects in the electromagnetic field of a resonator . His research focused on the limits of measurement accuracy caused by quantum mechanics and quantum nondemolition measurement . The resulting so-called quantum noise, which occurs as shot noise in special situations , was the subject of many of his investigations, which became of great importance for optics and nanotechnology .

Another research focus was the damping in mechanical systems, especially with regard to the investigation of gravitational waves . Together with his faculty colleagues, he developed essential elements for gravitational wave detectors , in particular a mass suspension with a relaxation time of more than 5 years. Braginski's research results were crucial for the successful work of the LIGO project. Braginski has been visiting professor at the California Institute of Technology since 1990 and worked with Kip Thorne and Rainer Weiss . Braginski was the author or co-author of a large number of publications.

Braganski was buried in the Wagankowo Cemetery .
