Unruh model for the Einstein-Rosen charge: Squealing Wormholes?
K. K. Nandi, D. H. Xu
We present two kinds of acoustic models for the massless electric charge conceived by Einstein and Rosen in the form of a bridge (wormhole throat). It is found that the first kind…
Acoustic Wormholes
Kamal Kanti Nandi, Yuan-Zhong Zhang, Rong-Gen Cai
Acoustic analogs of static, spherically symmetric massive traversable Lorentzian wormholes are constructed as a {\em formal} extension of acoustic black holes. The method is straig…
A Semiclassical ANEC Constraint On Classical Traversable Lorentzian Wormholes
Kamal K. Nandi, Yuan-Zhong Zhang, Nail G. Migranov
The present article lies at the interface between gravity, a highly nonlinear phenomenon, and quantum field theory. The nonlinear field equations of Einstein permit the theoretical…
Do Scalar Tensor Cosmologies naturally explain all the current cosmological observations ?
A. Bhadra, K. K. Nandi
It is shown that the general scalar tensor cosmologies may explain all the current cosmological observations without the need of invoking any ad hoc missing energy density. The exp…
