Some aspects of Microscopic Mechanism of Superconductivity in conventional and non-conventional systems
Ranjan Chaudhury, Koushik Mandal
A broad review of theoretical research work involving different types of microscopic mechanism in various classes of superconductors, carried out in our research group over a decad…
A Theoretical Analysis of Superconducting Pairing in Correlated Metallic Systems
Koushik Mandal, Ranjan Chaudhury
We have introduced a Coulomb correlated normal state to study the superconducting pairing with a Fermi liquid like normal phase background in a 3 dimensional system. The role of th…
Interplay of Pairing Correlation and Coulomb Correlation in Boson Exchange Superconductors
Koushik Mandal, Ranjan Chaudhury
A theoretical methodology for exploring the conventional Bardeen-Cooper-Schrieffer (BCS) pairing instability for superconductivity from a correlated normal phase for all possible d…
Study of effective coupling between charge degrees of freedom in low dimensional hole-doped quantum antiferromagnets
Suraka Bhattacharjee, Ranjan Chaudhury
Expressions for generalized charge stiffness constant at zero temperature are derived corresponding to low dimensional hole doped quantum antiferromagnets, describable by the t-J-l…
Theoretical investigation of the feasibility of electronic mechanism for superconducting pairing in overdoped cuprates with Fermi liquid like and Marginal Fermi liquid- like descriptions for the normal phase
Soumi Roy Chowdhury, Ranjan Chaudhury
Cooper's formalism for fermionic pairing has been revisited considering upto 3rd neighbour hopping terms, firstly with a Fermi liquid like background on a square lattice keeping in…
Effective interaction in a non-Fermi liquid conductor and spin correlations in under-doped cuprates
Suraka Bhattacharjee, Ranjan Chaudhury
The effective interaction between the itinerant spin degrees of freedom in the paramagnetic phases of hole doped quantum Heisenberg antiferromagnets is investigated theoretically,…
