Role of interlayer couplings in bilayer superconductors a variational monte carlo study

Abstract

The ground state superconducting and magnetic properties of bilayer cuprate superconductors are studied using a t J model with interlayer couplings using the variational Monte Carlo VMC method As a separate exercise but relevant to the single layers and ladder compounds a brief study of an impurity doped Hubbard model via the quantum Monte Carlo method is reported To settle a crucial question regarding the symmetry of the superconducting order parameter we investigated the stability of a
