Is Low Frequency Excess Noise of GMI Induced by Magnetization Fluctuations?

Detection of spin torque magnetization dynamics through low frequency noise

Fluctuations of 1/f noise and the low-frequency cutoff paradox.

Recent experiments on blinking quantum dots, weak turbulence in liquid crystals, and nanoelectrodes reveal the fundamental connection between 1/f noise and power law intermittency. The nonstationarity of the process implies that the power spectrum is random--a manifestation of weak ergodicity breaking. Here, we obtain the universal distribution of the power spectrum, which can be used to identi...

Excess low-frequency noise in AlGaNÕGaN-based high-electron-mobility transistors

The low-frequency 1/f noise characteristics of AlGaN/GaN high-electron-mobility transistors with gate length scaled down to 150 nm grown on sapphire by metalorganic chemical vapor deposition have been studied. Certain features of the 1/f noise have been revealed in these short-gate transistors. The low-frequency noise spectra show drastically different behavior depending on the gate voltage VG ...

Low frequency noise and annoyance.

Low frequency noise, the frequency range from about 10 Hz to 200 Hz, has been recognised as a special environmental noise problem, particularly to sensitive people in their homes. Conventional methods of assessing annoyance, typically based on A-weighted equivalent level, are inadequate for low frequency noise and lead to incorrect decisions by regulatory authorities. There have been a large nu...

Energy fluctuations induced by stochastic frequency changes in atom traps

Fluctuations of the electromagnetic fields used to trap or to modify the quantum state of trapped atoms are an important source of decoherence and limit the feasibility of manipulating atomic quantum states. This fact has given a renewed interest in the study of the effects of classical stochastic fields on quantum systems, in particular, the understanding of noise-induced heating in atom traps...
