 abstract = {We investigate the asymmetry between electron and hole doping in a 2D
Mott insulator and the resulting competition between antiferromagnetism
(AFM) and d-wave superconductivity (SC), using variational Monte Carlo
calculations for projected wave functions. We find that key features of
the T=0 phase diagram, such as critical doping for SC-AFM coexistence
and the maximum value of the SC order parameter, are determined by a
single parameter eta which characterizes the topology of the ``Fermi
surface″ at half filling defined by the bare tight-binding
parameters. Our results give insight into why AFM wins for electron
doping, while SC is dominant on the hole-doped side. We also suggest
using band structure engineering to control the eta parameter for
enhancing SC.},
