[1] He worked in the areas of precision and quantum measurements, the detection of gravitational waves, systems with low dissipation, and fundamental thermodynamic fluctuations.
He predicted and experimentally demonstrated ponderomotive effects of friction and stiffness in the electromagnetic field of the resonator (1967).
These effects underlie many modern developments in macroscopic quantum mechanics, in particular, optical and micro cooling nanooscillators to the zero state.
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.
