Description
We study a 3-dimensional SU(2) gauge theory with 4 Higgs fields which
transform under the adjoint representation of the gauge group,
that has been recently proposed by Sachdev et al. to explain the physics
of cuprate superconductors near optimal doping. The symmetric
confining phase of the theory corresponds to the usual
Fermi-liquid phase while the broken (Higgs) phase is associated
with the interesting pseudogap phase of cuprates. We employ the
Hybrid Monte-Carlo algorithm to study the phase diagram of the theory.
We find the existence of a variety of broken phases in accordance
with earlier mean-field predictions and discuss their role in cuprates.
