Equation B.1. van Gunstern-Berendsen Thermostat [16]


where

λis the temperature scaling factor
Δtis the timestep (time between iterations)
τTis a time constant
T0is the environment (bath) temperature
T(t-1/2Δt)is the temperature a half a timestep ago

The thermostat acts to realize coupling to an external bath with constant temperature, thereby maintaining a controllable temperature (the environmentTemperature variable in the simulation specification.)
