Global Inflow and Outflow Solutions (GIOS) around a Black Hole
Sandip K. Chakrabarti
Twenty five years have passed by since models of accretions and jets have separately emerged. Today, it is understood that these two objects are related to each other in a fundamen…
Self-Structuring of Granular Media under Internal Avalanches
S. Krishnamurthy, V. Loreto, H. J. Herrmann +2
We study the phenomenon of internal avalanching within the context of recently proposed ``Tetris'' lattice models for granular media. We define a recycling dynamics under which the…
Effect of dissipative forces on the theory of a single-atom microlaser
N. Nayak
We describe a one-atom microlaser involving Poissonian input of atoms with a fixed flight time through an optical resonator. The influence of the cavity reservoir during the intera…
Multifractal scaling of electronic transmission resonances in perfect and imperfect Fibonacci -function potentials
Prabhat K Thakur, Parthapratim Biswas
We present here a detailed multifractal scaling study for the electronic transmission resonances with the system size for an infinitely large one dimensional perfect and imperfect…
Computation of Mass Outflow Rate from Relativistic Quasi-Spherical Accretion onto Black Holes
Tapas K. Das
We compute mass outflow rate from relativistic matter accreting quasi-spherically onto Schwarzschild black holes. Taking the pair-plasma pressure mediated shock surfac…
Hamiltonian Analysis of Gauged Model, the Hopf term, and fractional spin
B. Chakraborty, A. S. Majumdar
Recently it was shown by Cho and Kimm that the gauged model, obtained by gauging the global group and adding a corresponding Chern-Simons term, has got its own solit…
