Arbitrary bending of optical solitonic beam regulated by boundary excitations in a doped resonant medium
Anjan Kundu, Tapan Naskar
Bending of a shape-invariant optical beam is achieved so far along parabolic or circular curves. Borrowing ideas used in nonlinear optical communication, we propose such a bending…
Black Hole spin dependence of general relativistic multi-transonic accretion close to the horizon
Tapas K. Das, Sankhasubhra Nag, Swathi Hegde +7
We introduce a novel formalism to investigate the role of the spin angular momentum of astrophysical black holes in influencing the behaviour of low angular momentum general relati…
Modelling rogue waves through exact dynamical lump soliton controlled by ocean currents
Anjan Kundu, Abhik Mukherjee, Tapan Naskar
Rogue waves are extraordinarily high and steep isolated waves, which appear suddenly in a calm sea and disappear equally fast. However, though the Rogue waves are localized surface…
Continuous transition of social efficiencies in the stochastic strategy Minority Game
Soumyajyoti Biswas, Asim Ghosh, Arnab Chatterjee +2
We show that in a variant of the Minority Game problem, the agents can reach a state of maximum social efficiency, where the fluctuation between the two choices is minimum, by foll…
Perturbations on steady spherical accretion in Schwarzschild geometry
Tapan Naskar, Nabajit Chakravarty, Jayanta K. Bhattacharjee +1
The stationary background flow in the spherically symmetric infall of a compressible fluid, coupled to the space-time defined by the static Schwarzschild metric, has been subjected…
Type I singularities and the Phantom Menace
Tapan Naskar, John Ward
We consider the future dynamics of a transient phantom dominated phase of the universe in LQC and in the RS braneworld, which both have a non-standard Friedmann equation. We find t…
