We use nonequilibrium molecular dynamics to
analyze and illustrate the qualitative differences between the
one-thermostat and two-thermostat versions of equilibrium and
nonequilibrium (heat-conducting) harmonic oscillators.
Conservative nonconducting regions can coexist with dissipative
heat conducting regions in phase space with exactly the same
imposed temperature field.
