  A d-wave superconducting phase with coexisting intra-unit-cell orbital
current order has the remarkable property that it supports finite size Fermi
pockets of Bougoliubov quasiparticles. Experimentally detectable consequences
of this include a residual $T$-linear term in the specific heat in the absence
of disorder and residual features in the thermal and microwave conductivity in
the low disorder limit.
