Symmetry breaking and singularity-free cosmology
The origin and the nature of the universe has intrigued the human mind since time immemorial. Till the beginning of this century, lack of observational data and the absence of a consistent theory of gravitation had precluded ... -
Some exact analytic models of time dependent collisionless stellar systems.
This thesis began with the general theme of studying the time-dependent behavior of collisionless self-gravitating systems. It is rather hard to obtain exact, general results by analytical methods (see Mathur 1986 for an ... -
Experimental investigations on metal-insulator transition and structure in amorphous carbon films
Conductivity of carbon films prepared from TCPA at pyrolysis temperatures of 700°C, 800°C, and 900°C was measured by varying the temperature between 1.4 K to 300 K. To study the effect of substrates, films were deposited ... -
Nonlinear analysis of lower hybrid by many-body techniques
In some recent experiments, intense ion heating has been observed. This heating has been attributed to the excitation of the lower hybrid in the inhomogeneous magnetoactive plasma. The level of turbulence is observed to ... -
Reactive diffusion in AI/Ge multilayers
It may be mentioned in this context that there is no evidence of the hexagonal and orthorhombic phase reported in e-beam annealed amorphous Al-Ge films in the present investigations. It is also interesting to note that the ...
