Fluctuation equation
WebAt finite temperature a phase transition is driven by thermal fluctuations, whereas in QPT at T = 0 some other nonthermal external parameters such as pressure, magnetic field, or chemical doping tune the quantum fluctuations of the system and thus drive it into the phase transition. WebMar 11, 2024 · e(t) = error b = bias In this equation, the bias and controller gain are constants specific to each controller. The bias is simply the controller output when the error is zero. The controller gain is the change in the output of the controller per change in the input to the controller.
