[1] He worked in the areas of precision and quantum measurements, the detection of gravitational waves, systems with low dissipation, and fundamental thermodynamic fluctuations.
These effects underlie many modern developments in macroscopic quantum mechanics, in particular, optical and micro cooling nanooscillators to the zero state.
It proves that units of the electron charge and the proton at 10−21 (1970) and demonstrated the validity of the equivalence principle at the level of 10−12 (1971).
Together with colleagues, he developed a number of key elements for the detectors of gravitational waves (both the bars and the laser interferometers), in particular the suspension of the proof mass with a relaxation time greater than 5 years.
Braginsky has also produced a large cadre of students: of the 34 PhD candidates prepared, 12 have achieved the Doctor of Science degree, including six professors working in various departments of the Faculty of Physics at Moscow State University.
