Geodesics in Information Geometry : Classical and Quantum Phase Transitions
Prashant Kumar, Subhash Mahapatra, Prabwal Phukon +1
We study geodesics on the parameter manifold, for systems exhibiting second order classical and quantum phase transitions. The coupled non-linear geodesic equations are solved nume…
Geodesic flows and their deformations in Bertrand spacetimes
Prashant Kumar, Kaushik Bhattacharya, Tapobrata Sarkar
In this article we will discuss some features of a particular spacetime called Bertrand space-time of Type II (BST-II). The talk discusses about the energy conditions and the ESR p…
Geodesic Congruences and Their Deformations in Bertrand Space-times
Prashant Kumar, Kaushik Bhattacharya, Tapobrata Sarkar
We study the energy conditions and geodesic deformations in Bertrand space-times. We show that these can be thought of as interesting physical space-times in certain regions of the…
