In STMD T 0 is called the kinetic temperature as it controls the velocities as usual, but does not enter the configurational sampling, which is unusual. Thus STMD can probe low energies with fast particles. Any canonical average can be calculated with reweighting, but the statistical temperature, T ( E ) , is immediately available with no additional analysis. It is extremely valuable for studying phase transitions. In finite nanosystems T ( E ) has a feature corresponding to every “subphase transition”. For a sufficiently strong transition, an equal-area construction on an S-loop in 1 / T ( E ) gives the transition temperature.
