Symmetry of the Gap Function in High- Superconductors
Mihir Arjunwadkar, D. G. Kanhere, G. Baskaran +1
One of the most debated issues related to high- superconductivity is the symmetry of the Cooper pair or the gap function. In this report, we present numerical results regardin…
Superconducting Gap Nodal Surface and Fermi Surface: their partial overlap in cuprates
G. Baskaran, D. G. Kanhere, Mihir Arjunwadkar +1
Electron correlation in cuprates leads to a global constraint on the gap function resulting in a gap nodal surface. We give physical argume…
Correlation Induced Vanishing of the Gap Function on the Fermi Surface in High Superconductors
G. Baskaran, D. G. Kanhere, Mihir Arjunwadkar +1
We present physical arguments as well as numerical evidence to show that the Cooper pair (gap) function vanishes on the Fermi surface in strongly correlated electron systems such a…
Numerical Study of the Wheatley-Hsu-Anderson Interlayer Tunneling mechanism of High Superconductivity
M. Arjunwadkar, G. Baskaran, R. Basu +1
We present results obtained (by exact diagonalization) for the problem of two t-J planes with an interlayer coupling . Our results for small hole concentrations show that…
