Hysteresis and Noise in Stripe and Clump Forming Systems

, 2005
We use simulations to examine hysteresis and noise in a model system that produces heterogeneous orderings including stripe and clump phases. In the presence of a disordered substrate, these heterogeneous phases exhibit 1/f$^\alpha$ noise and hysteresis ...

Sub-Poissonian Shot Noise In A Diffusive Conductor [PDF]

, 1994
A review is given of the shot-noise properties of metallic, diffusive conductors. The shot noise is one third of the Poisson noise, due to the bimodal distribution of transmission eigenvalues.

Strongly quadrature-dependent noise in superconducting micro-resonators measured at the vacuum-noise limit

, 2010
We measure frequency- and dissipation-quadrature noise in superconducting lithographed microwave resonators with sensitivity near the vacuum noise level using a Josephson parametric amplifier.

MONOLITHIC INTEGRATED CIRCUIT OF GаN LOW-NOISE AMPLIFIER FOR 57-64 GHz BANDWIDTH

Российский технологический журнал, 2016
The article describes the development of a low-noise amplifier for the 57-64 GHz band based on a wide-gap semiconductor - gallium nitride. We analyze existing commercial developments in the area of low-noise amplifiers for the 60 GHz band, which are ...

Efficient Magnetization Reversal with Noisy Currents

, 2005
We propose to accelerate reversal of the ferromagnetic order parameter in spin valves by electronic noise. By solving the stochastic equations of motion we show that the current-induced magnetization switching time is drastically reduced by a modest ...

Frequency-Dependent Shot Noise as a Probe of Electron-Electron Interaction in Mesoscopic Diffusive Contacts

, 1998
The frequency-dependent shot noise in long and narrow mesoscopic diffusive contacts is numerically calculated. The case of arbitrarily strong electron-electron scattering and zero temperature of electrodes is considered.
