Ideal gas with a varying (negative absolute) temperature: An alternative to dark energy?
Subhajit Saha, Anindita Mondal, Christian Corda
The present work is an attempt to investigate whether the evolutionary history of the Universe from the offset of inflation can be described by assuming the cosmic fluid to be an i…
Interacting Chaplygin gas revisited
Subhajit Saha, Saumya Ghosh, Sunandan Gangopadhyay
The implications of considering interaction between Chaplygin gas and a barotropic fluid with constant equation of state have been explored. The unique feature of this work is that…
Particle creation and non-equilibrium thermodynamical prescription of dark fluids for universe bounded by an event horizon
Subhajit Saha, Atreyee Biswas, Subenoy Chakraborty
In the present work, flat FRW model of the universe is considered to be an isolated open thermodynamical system where non-equilibrium prescription has been studied using the mechan…
Particle Production and Universal Thermodynamics
Subhajit Saha, Subenoy Chakraborty
In the present work, particle creation mechanism has been employed to the Universe as a thermodynamical system. The Universe is considered to be a spatially flat FRW model and cosm…
Thermodynamics of the inhomogeneous perfect fluid LTB model: Modified Bekenstein-Hawking system
Subhajit Saha, Subenoy Chakraborty
The present work deals with three alternative generalized Bekenstein-Hawking formulation of thermodynamical parameters namely entropy and temperature for the universal thermodynami…
Do recent observations favor a cosmological event horizon: A thermodynamical prescription?
Subhajit Saha, Subenoy Chakraborty
Recent observational evidences claim an accelerating expansion of the universe at present epoch. It is commonly incorporated in standard cosmology by the introduction of an exotic…
