PUBLIC ENTERPRISES---CORPORATE GOVERNANCE AND THE ROLE OF GOVERNMENT

Public sector occupies a prominent position in the Indian economy. The present government policy is to divest its holding in PSUs, without privatizing profit making PSUs. It has also decided to provide full autonomy to the board of directors of those enterprises. This provides an interesting setting to examine corporate governance issues. This paper examines corporate governance issues in the context of present disinvestment policy of the government.Public Sector Enterprises, State-Owned Enterprises

Model study of hot and dense baryonic matter

The properties of baryonic matter have been investigated at finite density and temperature using different models. The variation of baryon masses and fractional number densities with baryon density and temperature obtained from different models have been compared. The quark hadron phase transition have been studied using Chiral Colour Dieletric (CCD) model in the quark sector. No phase transition has been seen for the different variants of the Zimanyi-Moszkowski model. However, a phase transition is observed for the linear and non-linear Walecka model.Comment: Latex, 16 postscript figures available on reques

Scaling Function for the Critical Specific Heat in a Confined Geometry : Spherical Limit

The scaling function for the critical specific heat is obtained exactly for temperatures above the bulk transition temperature by working in the spherical limit. Generalization of the function to arbitrary $\alpha$ (the specific heat exponent), gives an excellent account of the experimental data of Mehta and Gasparini near the superfluid transition.Comment: 11 pages (LaTeX), 2 figures (PostScript

Semiconductor-metal transition in semiconducting bilayer sheets of transition metal dichalcogenides

Using first-principles calculations we show that the band gap of bilayer sheets of semiconducting transition metal dichalcogenides (TMDs) can be reduced smoothly by applying vertical compressive pressure. These materials undergo a universal reversible semiconductor to metal (S-M) transition at a critical pressure. S-M transition is attributed to lifting the degeneracy of the bands at fermi level caused by inter-layer interactions via charge transfer from metal to chalcogens. The S-M transition can be reproduced even after incorporating the band gap corrections using hybrid functionals and GW method. The ability to tune the band gap of TMDs in a controlled fashion over a wide range of energy, opens-up possibility for its usage in a range of applications.Comment: Accepted in Phys. Rev.
