Query: Fermion mass generation without a condensate   We study a lattice field theory model containing two flavors of massless
staggered fermions with an onsite four-fermion interaction. The symmetry of the
model forbids non-zero fermion bilinear order parameters that can generate a
fermion mass. At weak couplings, we expect a massless fermion phase. At strong
couplings, we can argue for the existence of massive fermions without the
formation of any fermion bilinear condensate. Using Monte Carlo calculations in
three space-time dimensions, we find evidence for a direct second order phase
transition between the two phases.
