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…
Investigation of fermionic pairing on two- dimensional tight binding lattice under phonon and electronic mechanisms within a simple Fermi liquid like scenario and beyond- possible consequences for superconductivity in overdoped cuprates
Soumi Roy Chowdhury, Ranjan Chaudhury
Cooper's one pair problem is investigated for a 2D lattice in the background of both passive and active Fermi sea in a weakly correlated environment. Boson exchange mechanisms invo…
Investigation of fermionic pairing on tight binding lattice for low dimensional systems
Soumi Roy Chowdhury, Ranjan Chaudhury
Cooper's original one pair problem in continuum is revisited here corresponding to a lattice of tight binding nature, with an aim to investigate superconductivity in low dimensiona…
Can Excitonic Mechanism Contribute Significantly to Superconducting Pairing in Quasi 1-D Systems?
Soumi Roy Chowdhury, Ranjan Chaudhury
We have revisited Cooper's one pair problem of calculating the binding energy for two electrons, experiencing an attractive interaction near the Fermi surface, in case of quasi one…
