Brans wormholes
Kamal K. Nandi, Anwarul Islam
It is shown that three of the four Brans solutions of classes I--IV admit wormhole geometry. Two-way traversable wormholes in the Brans-Dicke theory are allowed not only for the ne…
Brans-Dicke wormholes in the Jordan and Einstein frames
K. K. Nandi, B. Bhattacharjee, S. M. K. Alam +1
We examine the possibility of static wormhole solutions in the vacuum Brans-Dicke theory both in the original (Jordan) frame and in the conformally rescaled (Einstein) frame. It tu…
New Features of Extended Wormhole Solutions in the Scalar Field Gravity Theories
Kamal K. Nandi, Ilnur Nigmatzyanov, Ramil Izmailov +1
The present paper reports interesting new features that wormhole solutions in the scalar field gravity theory have. To demonstrate these, we obtain, by using a slightly modified fo…
An Algorithm for Generating Rotating Brans-Dicke Wormhole Solutions
Kamal K. Nandi, Yuan-Zhong Zhang
Using the ansatz of Matos and Núñez, the present article proposes an algorithm for generating several classes, not all independent, of asymptotically flat rotating wormhole solutio…
Gravitational Lensing by Wormholes
Kamal Kanti Nandi, Yuan-Zhong Zhang, Alexander V. Zakharov
Gravitational lensing by traversable Lorentzian wormholes is a ew possibility which is analyzed here in the strong field limit. Wormhole solutions are considered in the Einstein mi…
Planetary and Light Motions From Newtoinian Theory: An Amusing Exercise
K. K. Nandi, N. G. Migranov, J. C. Evans +1
We attempt to see how closely we can formally obtain the planetary and light path equations of General Relativity by employing certain operations on the familiar Newtonian equation…
