First Order Phase Transition in Quantum Paraelectrics
Nabyendu Das, Suresh G. Mishra
We discuss the nature of pressure induced phase transitions in standard Quantum Paraelectrics near quantum critical point. From a microscopic theory we first show that near the cri…
Fluctuations and Criticality in Quantum Paraelectrics
Nabyendu Das, Suresh G. Mishra
The temperature dependence of static dielectric susceptibility of a system with strongly coupled fluctuating dipoles is calculated within a self consistent mean fluctuation field a…
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 some correlated Fermion systems
Suresh G. Mishra, P. A. Sreeram
Specific heat versus temperature curves for various pressures, or magnetic fields (or some other external control parameter) have been seen to cross at a point or in a very small r…
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…
Fluctuation Induced Non-Fermi Liquid Behavior near a Quantum Phase Transition in Itinerant Electron Systems
Suresh G. Mishra, P. A. Sreeram
The signature for a non-Fermi liquid behavior near a quantum phase transition has been observed in thermal and transport properties of many metallic systems at low temperatures. In…
