Wormhole generating function in gravity
Bikram Ghosh, Saugata Mitra
In this present work, we have studied the traversable wormhole geometries in gravity theory, where denotes the Ricci scalar and is the trace of the energy-momentum…
A new shape function and some specific wormhole solutions in braneworld scenario
Bikram Ghosh, Saugata Mitra
Considering a energy density of the form ( where is an arbitrary positive constant with dimension of energy density and ), a shape fu…
Wormhole solutions in gravity theory for Chaplygin gas scenario
Bikram Ghosh, Saugata Mitra
The present paper deals with some wormhole solutions which are obtained by taking two different shape functions along with zero tidal force. For obtaining wormhole solutions, aniso…
Some specific wormhole solutions in -modified gravity theory
Bikram Ghosh, Saugata Mitra, Subenoy Chakraborty
The paper deals with the static spherically symmetric wormhole solutions in -modified gravity theory with anisotropic matter field and for some particular choices for the sha…
A Study of Universal Thermodynamics in Massive Gravity: Modified Entropy on the Horizons
Subhajit Saha, Saugata Mitra, Subenoy Chakraborty
Universal thermodynamics for FRW model of the Universe bounded by apparent/event horizon has been considered for massive gravity theory. Assuming Hawking temperature and using the…
A Study of Universal Thermodynamics in Lanczos-Lovelock gravity
Saugata Mitra, Subhajit Saha, Subenoy Chakraborty
A study of Universal thermodynamics is done in Lanczos-Lovelock gravity. The Universe is chosen as FRW model bounded by apparent or event horizon. The unified first law is examined…
Universal thermodynamics in different gravity theories: Conditions for generalized second law of thermodynamics and thermodynamical equilibrium on the horizons

Modified Hawking temperature and entropic force: a prescription in FRW model
Saugata Mitra, Subhajit Saha, Subenoy Chakraborty
The idea of Verlinde that gravity is an entropic force caused by information changes associated with the positions of material bodies, is used in the present work for the FRW model…
Modified Bekenstein-Hawking system in gravity
Jibitesh Dutta, Saugata Mitra, Binod Chetry
The present work deals with four alternative formulation of Bekenstein system on event horizon in gravity. While thermodynamical laws holds in universe bounded by apparent h…
