Beltrami state in black-hole accretion disk: A magnetofluid approach
Chinmoy Bhattacharjee, Rupam Das, David J. Stark +1
Using the magnetofluid unification framework, we show that the accretion disk plasma (embedded in the background geometry of a blackhole) can relax to a class of states known as th…
Spatial modulation of the composition of a binary liquid near a repulsive wall
Shibu Saw, S. M. Kamil, Chandan Dasgupta
When a binary liquid is confined by a strongly repulsive wall, the local density is depleted near the wall and an interface similar to that between the liquid and its vapor is form…
Parametric symmetries in exactly solvable real and P T symmetric complex potentials
Rajesh Kumar Yadav, Avinash Khare, Bijan Bagchi +2
In this paper, we discuss the parametric symmetries in different exactly solvable systems characterized by real or complex P T symmetric potentials. We focus our at- tention on the…
A model of discrete Kolmogorov-type competitive interaction in a two-species ecosystem
Sudeepto Bhattacharya, L. M. Saha
An ecosystem is a nonlinear dynamical system, its orbits giving rise to the observed complexity in the system. The diverse components of the ecosystem interact in discrete time to…
Exact evaluations of some Meijer G-functions and probability of all eigenvalues real for product of two Gaussian matrices
Santosh Kumar
We provide a proof to a recent conjecture by Forrester [2014 J. Phys. A: Math. Theor. 47, 065202] regarding the algebraic and arithmetic structure of Meijer G-functions which appea…
Novel mechanism for vorticity generation in black-hole accretion disks
Chinmoy Bhattacharjee, Rupam Das, Swadesh M. Mahajan
Vorticity generation in accretion disks around Schwarzschild and Kerr black holes is investigated in the context of magnetofluid dynamics derived for both General Relativity (GR),…
