Zermelo Wind: a geometrization of the frame dragging effect
Sumanto Chanda
In this article I discuss Zermelo's navigation problem in spacetime as a geometrization of the frame dragging effect, and recast various examples involving the latter into Zermelo…
Mechanics of geodesics in Information geometry and Black Hole Thermodynamics
Sumanto Chanda, Tatsuaki Wada
In this article we shall discuss the theory of geodesics in information geometry, and an application in astrophysics. We will study how gradient flows in information geometry descr…
Optical properties of null geodesics emerging from dynamical systems
D. Batic, S. Chanda, P. Guha
We study optical metrics via null geodesics as a central force system, deduce the related Binet equation and apply the analysis to certain solutions of Einstein's equations with an…
More on Jacobi metric: Randers-Finsler metrics, frame dragging and geometrisation techniques
Sumanto Chanda
In this article, I demonstrate a new method to derive Jacobi metrics from Randers-Finsler metrics by introducing a more generalised approach to Hamiltonian mechanics for such space…
Eisenhart lift and Randers-Finsler formulation for scalar field theory
Sumanto Chanda, Partha Guha
We study scalar field theory as a generalization of point particle mechanics using the Polyakov action, and demonstrate how to extend Lorentzian and Riemannian Eisenhart lifts to t…
Jacobi-Maupertuis Randers-Finsler metric for curved spaces and the gravitational magnetoelectric effect
Sumanto Chanda, G. W. Gibbons, Partha Guha +2
In this paper we return to the subject of Jacobi metrics for timelike and null geodsics in stationary spactimes, correcting some previous misconceptions. We show that not only null…
