A simple mechanical analog of the field theory of tachyon matter
Sayan Kar
In this brief note we show that the zero dimensional version of the field theory of tachyon matter proposed by Sen, provides an action integral formulation for the motion of a part…

Static spherisymmetric solutions, gravitational lensing and perihelion precession in Einstein--Kalb--Ramond theory
Sayan Kar, Soumitra SenGupta, Saurabh Sur
Static, spherically symmetric solutions of the Einstein--Kalb--Ramond (KR) field equations are obtained. Besides an earlier known exact solution, we also find an approximate, asymp…

Asymmetrically warped R=0 braneworlds
Sayan Kar
A new family of five dimensional, R=0 braneworlds with asymmetric warp factors is proposed. Beginning with the invariance of the Ricci scalar for the general class of asymmetricall…
