Self Similar Collapse and the Raychaudhuri equation
Shibendu Gupta Choudhury, Soumya Chakrabarti, Ananda Dasgupta +1
The role of the Raychaudhuri equation in studying gravitational collapse is discussed. A self-similar distribution of a scalar field along with an imperfect fluid in a conformally…
Limiting distribution of periodic position measurements of a quantum harmonic oscillator
Arnab Acharya, Debapriya Pal, Soumitro Banerjee +1
We consider a particle in harmonic oscillator potential, whose position is periodically measured with an instrument of finite precision. We show that the distribution of the measur…
Thawing and Freezing Quintessence Models: A thermodynamic Consideration
Tanima Duary, Ananda Dasgupta Narayan Banerjee
Thawing and freezing quintessence models are compared thermodynamically. Both of them are found to disobey the Generalized Second Law of Thermodynamics. However, for freezing model…
Reconstruction of gravity models for an accelerated universe using Raychaudhuri equation
Shibendu Gupta Choudhury, Ananda Dasgupta, Narayan Banerjee
A new strategy for the reconstruction of gravity models have been attempted using Raychaudhuri equation. Two examples, one for an eternally accelerating universe and the oth…
