By analyzing the bumps in the cosmic microwaves, which according to inflation are the result of microscopic fluctuations in the mysterious force field that drove inflation, along with other data, Dr. Spergel said, the scientists have ruled out one simple version of inflation that is often seen in textbooks.
Therefore, the fluctuations in the wire are the direct signal of the microscopic fluctuations in EPS domains at the transition temperature.
These microscopic fluctuations induced by the external perturbation are at the origin of the local-field effects (LF) and reflect the spatial anisotropy of the material.
Slight temperature deviations in what is otherwise an exceedingly uniform heat bath are thought to arise from microscopic fluctuations in a force field known as inflation that drove the expansion of the universe when it was but a sliver of a nanosecond old.
It was shown that over a wide range of experimental conditions, macroscopically steady reaction fronts in heterogeneous mixtures exhibit random microscopic fluctuations in shape and instantaneous velocity, which are directly related to the microstructure of the reaction mixture.
In a sense, our work can be thought of providing a formal justification of the commonly encountered intuition that bulk properties should be immune to microscopic fluctuations, and elucidating the connection between this intuition and system symmetries.
Nevertheless, due to the absence of the microscopic fluctuation, Biot׳s model with the parameters obtained from the homogenization approach predicts a higher resonance frequency than the DNS, whereas a full homogenization modification improves the prediction.
At any given moment, at any given location, the energy distributed in matter will betray incredibly tiny, sub-microscopic fluctuations, whose expected behavior physicists can calculate.
The emphasis of the theory is on the fluctuations of the microscopic charge density at equilibrium.
Hence, this quantum simulation model will be robust to parameters deviations as long as these two sums are maintained at zero; i.e., local fluctuations of the microscopic parameters that (spatially) average to zero are inconsequential.
