  abstract={A quantum mechanical model is used to attempt to explain the deviation from expected classical
behaviour of measurements of the superfluid fractions of a YBCO-type material. The superfluid
fractions are calculated from three typical models of the superconducting material
YBa$_2$Cu$_3$O$_{7-\delta}$. This is done using a quantum
mechanical model based on the Josephson coupling between superconducting grains and the
charging effects associated with the fluctuating number of Cooper pairs on the individual
grains. Several strengths of the charging effect are examined at low temperatures for each
model.},
