Generation of Non-Equilibrium 1⁄f Temperature Noise

抄録

Experimental study is given of non-equilibrium stationary 1⁄f temperature noise. A previous theory predicts that one-dimensional or quasi one-dimensional thermal conductor generates, under proper conditions, the 1⁄f temperature noise, when input heat fluctuates with a white spectrum. The prediction is confirmed by experiments on a thin and long enough cylindrical copper. In passing it is shown explicitly that this noise is related to a time-scale invariant relaxation.
