A curious variant of Bronnikov-Ellis spacetime
Sayan Kar
We explore a curious but simple variant of the Bronnikov-Ellis (BE) wormhole spacetime with a specific `red-shift function' (i.e. ) in the line element. The matter required…

A wormhole geometry from gravitational collapse
Soumya Chakrabarti, Sayan Kar
We discuss a proposal on how gravitational collapse of a NEC (Null Energy Condition) violating spherically symmetric fluid distribution can avoid the formation of a zero proper vol…

Analog Raychaudhuri equation in mechanics
Rajendra Prasad Bhatt, Anushree Roy, Sayan Kar
Usually, in mechanics, we obtain the trajectory of a particle in a given force field by solving Newton's second law with chosen initial conditions. In contrast, through our work he…
