A look at the crossover region between BCS superconductivity and Bose Einstein Condensation
P. A. Sreeram, Suresh G. Mishra
Pair fluctuation theory has been used to study the crossover from the weak coupling BCS theory to the strong coupling Bose Einstein Condensation. The effect of fluctuations has bee…

Crossing of Specific Heat Curves in Liquid Helium 3 and Heavy Fermion Systems
Suresh G. Mishra, P. A. Sreeram
Specific heat curves for various pressures, in many correlated electron systems, have been seen to cross at a point. We analyze this behavior using the spin fluctuation theory. It…
