Measuring inertial mass with Kibble balance
Rajendra P. Gupta
A Kibble balance measures the mass (weight) of a test mass with extreme precision by balancing the gravitational pull on the test mass against the electromagnetic l…
Dynamical analysis of the covarying coupling constants in scalar-tensor gravity
Rodrigo R. Cuzinatto, Rajendra P. Gupta, Pedro J. Pompeia
A scalar-tensor theory of gravity is considered wherein the gravitational coupling and the speed of light are admitted as space-time functions and combine to form the defin…
Constraining variability of coupling constants with bright and extreme quasars
Rajendra P. Gupta
The 'extreme Population A (xA) quasars' approaching, sometimes exceeding the Eddington limit, are a type of quasars that could serve as a standard candle to measure distances too l…
Varying Coupling Constants and Their Interdependence
Rajendra P Gupta
Since Dirac predicted in 1937 possible variation of gravitational constant and other coupling constants from his large number hypothesis, efforts continue to determine such variati…
