  In a closely packed ensemble of quantum emitters, cooperative effects are
typically suppressed due to the dephasing induced by the dipole-dipole
interactions. Here, we show that by adding sufficiently strong collective
dephasing cooperative effects can be restored. In particular, we show that the
dipole force on a closely packed ensemble of strongly driven two-level quantum
emitters, which collectively dephase, is enhanced in comparison to the dipole
force on an independent non-interacting ensemble. Our results are relevant to
solid state systems with embedded quantum emitters such as colour centers in
diamond and superconducting qubits in microwave cavities and waveguides.
