Fast Transition between High-soft and Low-soft States in GRS 1915+105: Evidence for a Critically Viscous Accretion Flow
S. Naik, A. R. Rao, Sandip K. Chakrabarti
We present the results of a detailed analysis of RXTE observations of class which show an unusual state transition between high-soft and low-soft states in the microquasar GRS…
Electronic and Optical Properties of ZnInTe
Biplab Ganguli, Kamal Krishna Saha, Tanusri Saha-Dasgupta +2
Band structure and optical properties of defect- Chalcopyrite type semiconductor ZnInTe have been studied by TB-LMTO first principle technique. The optical absorption calcu…
Gauge Transformations, BRST Cohomology and Wigner's Little Group
R. P. Malik
We discuss the (dual-)gauge transformations and BRST cohomology for the two (1 + 1)-dimensional (2D) free Abelian one-form and four (3 + 1)-dimensional (4D) free Abelian 2-form gau…
Thermally Driven Outflows from Pair-Plasma Pressure Mediated Shock Surfaces around Schwarzschild Black Holes
Tapas Kumar Das
Introducing a spherical, steady, self-supported pair-plasma pressure mediated shock surface around a Schwarzschild black hole as the effective physical atmosphere which may be resp…
Wigner's Little Group as a Generator of Gauge Transformations
Rabin Banerjee
The role of Wigner's little group, as an abelian gauge generator in different contexts, is studied.
The appearence of the resolved singular hypersurface {x_0}{x_1}-{{x_2}^n} =0 in the classical phase space of the Lie group SU(n)
Samir K. Paul, Siddhartha Sen
A classical phase space with a suitable symplectic structure is constructed together with functions which have Poisson brackets algebraically identical to the Lie algebra structure…
