Query: Heat Conduction, and the Lack Thereof, in Time-Reversible Dynamical
  Systems: Generalized Nos\'e-Hoover Oscillators with a Temperature Gradient   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.
