摘要：We study a quenched SU(2) lattice gauge theory in 4d in which the spatial gauge ensemble {Ui}
is generated from a 3d gauge-Higgs model and the timelike link variables are “reconstructed”
from the Higgs fields. The resulting ensemble is used to study quenched quark propagation with
non-zero chemical potential m. While it proves possible to alter the strength of the inter-quark
interaction by changing the parameters of the dimensionally reduced model, there is no evidence
for any region of parameter space where quarks exhibit deconfined behaviour or thermodynamic
observables scale as if there were a Fermi surface.
